The Indo-European languages are a language family native to the overwhelming majority of Europe, the Iranian plateau, and the northern Indian subcontinent. Some European languages of this family, English, French, Portuguese, Russian, Dutch, and Spanish, have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, of which there are eight groups with languages still alive today: Albanian, Armenian, Balto-Slavic, Celtic, Germanic, Hellenic, Indo-Iranian, and Italic; and another nine subdivisions that are now extinct. Today, the individual Indo-European languages with the most native speakers are English, Hindi–Urdu, Spanish, Bengali, French, Russian, Portuguese, German, and Punjabi, each with over 100 million native speakers; many others are small and in danger of extinction. In total, 46% of the world's population (3.2 billion people) speaks an Indo-European language as a

The analysis of the family relationships between the Indo-European languages, and the reconstruction of their common source, was central to the development of the methodology of historical linguistics as an academic discipline in the 19th century. The Indo-European family is not known to be linked to any other language family through any more distant genetic relationship, although several disputed proposals to that effect have been made.


History of Indo-European linguistics

During the 16th century, European visitors to the Indian subcontinent began to notice similarities among Indo-Aryan, Iranian, and European languages. In 1583, English Jesuit missionary and Konkani scholar Thomas Stephens wrote a letter from Goa to his brother (not published until the 20th century) in which he noted similarities between Indian languages and Greek and

However, neither Stephens' nor Sassetti's observations led to further scholarly inquiry. In 1647, Dutch linguist and scholar Marcus Zuerius van Boxhorn noted the similarity among certain Asian and European languages and theorized that they were derived from a primitive common language which he called Scythian. He included in his hypothesis Dutch, Albanian, Greek,

, Persian, and German, later adding Slavic, Celtic, and Baltic languages. However, Van Boxhorn's suggestions did not become widely known and did not stimulate further research. Ottoman Turkish traveler Evliya Çelebi visited Vienna in 1665–1666 as part of a diplomatic mission and noted a few similarities between words in German and in Persian. Gaston Coeurdoux and others made observations of the same type. Coeurdoux made a thorough comparison of Sanskrit, Latin and Greek conjugations in the late 1760s to suggest a relationship among them. Meanwhile, Mikhail Lomonosov compared different language groups, including Slavic, Baltic (" Kurlandic"), Iranian (" Medic"), Finnish, Chinese, "Hottentot" ( Khoekhoe), and others, noting that related languages (including Latin, Greek, German and Russian) must have separated in antiquity from common ancestors.M.V. Lomonosov (drafts for ''Russian Grammar'', published 1755). In: Complete Edition, Moscow, 1952, vol. 7, pp. 652–59

The hypothesis reappeared in 1786 when William Jones (philologist), Sir William Jones first lectured on the striking similarities among three of the oldest languages known in his time:

, to which he tentatively added Gothic, Celtic, and Persian, though his classification contained some inaccuracies and omissions. In one of the most famous quotations in linguistics, Jones made the following prescient statement in a lecture to the Asiatic Society of Bengal in 1786, conjecturing the existence of an earlier ancestor language, which he called "a common source" but did not name: Thomas Young first used the term ''Indo-European'' in 1813, deriving it from the geographical extremes of the language family: from Western Europe to North India. A synonym is Indo-Germanic (''Idg.'' or ''IdG.''), specifying the family's southeasternmost and northwesternmost branches. This first appeared in French (''indo-germanique'') in 1810 in the work of Conrad Malte-Brun; in most languages this term is now dated or less common than ''Indo-European'', although in German ''indogermanisch'' remains the standard scientific term. A number of other synonymous terms have also been used. Franz Bopp wrote in 1816 ''On the conjugational system of the Sanskrit language compared with that of Greek, Latin, Persian and Germanic'' and between 1833 and 1852 he wrote ''Comparative Grammar''. This marks the beginning of

as an academic discipline. The classical phase of Indo-European comparative linguistics leads from this work to August Schleicher's 1861 ''Compendium'' and up to Karl Brugmann's '' Grundriss'', published in the 1880s. Brugmann's neogrammarian reevaluation of the field and Ferdinand de Saussure's development of the laryngeal theory may be considered the beginning of "modern" Indo-European studies. The generation of Indo-Europeanists active in the last third of the 20th century (such as Calvert Watkins, Jochem Schindler, and Helmut Rix) developed a better understanding of morphology and of ablaut in the wake of Kuryłowicz's 1956 ''Apophony in Indo-European,'' who in 1927 pointed out the existence of the Hittite consonant ḫ. Kuryłowicz's discovery supported Ferdinand de Saussure's 1879 proposal of the existence of ''coefficients sonantiques'', elements de Saussure reconstructed to account for vowel length alternations in Indo-European languages. This led to the so-called laryngeal theory, a major step forward in Indo-European linguistics and a confirmation of de Saussure's theory.

Extant in two dialects (Turfanian and Kuchean, or Tocharian A and B), attested from roughly the 6th to the 9th century AD. Marginalized by the Old Turkic Uyghur Khaganate and probably extinct by the 10th century. In addition to the classical ten branches listed above, several extinct and little-known languages and language-groups have existed or are proposed to have existed: * Ancient Belgian: hypothetical language associated with the proposed Nordwestblock cultural area. Speculated to be connected to Italic or Venetic, and to have certain phonological features in common with Lusitanian. * Cimmerian: possibly Iranic, Thracian, or Celtic * Dacian: possibly very close to Thracian * Elymian: Poorly-attested language spoken by the Elymians, one of the three indigenous (i.e. pre-Greek and pre-Punic) tribes of Sicily. Indo-European affiliation widely accepted, possibly related to Italic or Anatolian.] * Illyrian: possibly related to Albanian, Messapian, or both * Liburnian language, Liburnian: evidence too scant and uncertain to determine anything with certainty * Ligurian: possibly close to or part of Celtic. * Lusitanian: possibly related to (or part of) Celtic, Ligurian, or Italic * Ancient Macedonian: proposed relationship to Greek. * Messapian: not conclusively deciphered * Paionian: extinct language once spoken north of Macedon * Phrygian: language of the ancient Phrygians. Very likely, but not certainly, a sister group to Hellenic. * Sicel: an ancient language spoken by the Sicels (Greek Sikeloi, Latin Siculi), one of the three indigenous (i.e. pre-Greek and pre-Punic) tribes of Sicily. Proposed relationship to Latin or proto-Illyrian (Pre-Indo-European) at an earlier stage. * Sorothaptic: proposed, pre-Celtic, Iberian language * Thracian: possibly including Dacian * Venetic: shares several similarities with Latin and the Italic languages, but also has some affinities with other IE languages, especially Germanic and Celtic. Membership of languages in the Indo-European language family is determined by genealogical relationships, meaning that all members are presumed descendants of a common ancestor, Proto-Indo-European. Membership in the various branches, groups and subgroups of Indo-European is also genealogical, but here the defining factors are ''shared innovations'' among various languages, suggesting a common ancestor that split off from other Indo-European groups. For example, what makes the Germanic languages a branch of Indo-European is that much of their structure and phonology can be stated in rules that apply to all of them. Many of their common features are presumed innovations that took place in

, the source of all the Germanic languages. In the 21st century, several attempts have been made to model the phylogeny of Indo-European languages using Bayesian methodologies similar to those applied to problems in biological phylogeny. Although there are differences in absolute timing between the various analyses, there is much commonality between them, including the result that the first known language groups to diverge were the Anatolian and Tocharian language families, in that order.


Tree versus wave model

The " tree model" is considered an appropriate representation of the genealogical history of a language family if communities do not remain in contact after their languages have started to diverge. In this case, subgroups defined by shared innovations form a nested pattern. The tree model is not appropriate in cases where languages remain in contact as they diversify; in such cases subgroups may overlap, and the " wave model" is a more accurate representation. Most approaches to Indo-European subgrouping to date have assumed that the tree model is by-and-large valid for Indo-European; however, there is also a long tradition of wave-model approaches. In addition to genealogical changes, many of the early changes in Indo-European languages can be attributed to language contact. It has been asserted, for example, that many of the more striking features shared by Italic languages (Latin, Oscan, Umbrian, etc.) might well be areal features. More certainly, very similar-looking alterations in the systems of long vowels in the West Germanic languages greatly postdate any possible notion of a proto-language innovation (and cannot readily be regarded as "areal", either, because English and continental West Germanic were not a linguistic area). In a similar vein, there are many similar innovations in Germanic and Balto-Slavic that are far more likely areal features than traceable to a common proto-language, such as the uniform development of a high vowel (*''u'' in the case of Germanic, *''i/u'' in the case of Baltic and Slavic) before the PIE syllabic resonants *''ṛ, *ḷ, *ṃ, *ṇ'', unique to these two groups among IE languages, which is in agreement with the wave model. The Balkan sprachbund even features areal convergence among members of very different branches. An extension to the '' Ringe- Warnow model of language evolution'', suggests that early IE had featured limited contact between distinct lineages, with only the Germanic subfamily exhibiting a less treelike behaviour as it acquired some characteristics from neighbours early in its evolution. The internal diversification of especially West Germanic is cited to have been radically non-treelike.


Proposed subgroupings

Specialists have postulated the existence of higher-order subgroups such as Italo-Celtic, Graeco-Armenian, Graeco-Aryan or Graeco-Armeno-Aryan, and Balto-Slavo-Germanic. However, unlike the ten traditional branches, these are all controversial to a greater or lesser degree. The Italo-Celtic subgroup was at one point uncontroversial, considered by Antoine Meillet to be even better established than Balto-Slavic. The main lines of evidence included the genitive suffix ''-ī''; the superlative suffix ''-m̥mo''; the change of /p/ to /kʷ/ before another /kʷ/ in the same word (as in ''penkʷe'' > ''*kʷenkʷe'' > Latin ''quīnque'', Old Irish ''cóic''); and the subjunctive morpheme ''-ā-''. This evidence was prominently challenged by Calvert Watkins, while Michael Weiss has argued for the subgroup. Evidence for a relationship between Greek and Armenian includes the regular change of the second laryngeal to ''a'' at the beginnings of words, as well as terms for "woman" and "sheep". Greek and Indo-Iranian share innovations mainly in verbal morphology and patterns of nominal derivation. Relations have also been proposed between Phrygian and Greek, and between Thracian and Armenian. Some fundamental shared features, like the aorist (a verb form denoting action without reference to duration or completion) having the perfect active particle -s fixed to the stem, link this group closer to Anatolian languages and Tocharian. Shared features with Balto-Slavic languages, on the other hand (especially present and preterit formations), might be due to later contacts. The Indo-Hittite hypothesis proposes that the Indo-European language family consists of two main branches: one represented by the Anatolian languages and another branch encompassing all other Indo-European languages. Features that separate Anatolian from all other branches of Indo-European (such as the gender or the verb system) have been interpreted alternately as archaic debris or as innovations due to prolonged isolation. Points proffered in favour of the Indo-Hittite hypothesis are the (non-universal) Indo-European agricultural terminology in Anatolia and the preservation of laryngeals. However, in general this hypothesis is considered to attribute too much weight to the Anatolian evidence. According to another view, the Anatolian subgroup left the Indo-European parent language comparatively late, approximately at the same time as Indo-Iranian and later than the Greek or Armenian divisions. A third view, especially prevalent in the so-called French school of Indo-European studies, holds that extant similarities in non- satem languages in general—including Anatolian—might be due to their peripheral location in the Indo-European language-area and to early separation, rather than indicating a special ancestral relationship. Hans J. Holm, based on lexical calculations, arrives at a picture roughly replicating the general scholarly opinion and refuting the Indo-Hittite hypothesis.


Satem and centum languages

The division of the Indo-European languages into satem and centum groups was put forward by Peter von Bradke in 1890, although Karl Brugmann did propose a similar type of division in 1886. In the satem languages, which include the Balto-Slavic and Indo-Iranian branches, as well as (in most respects) Albanian and Armenian, the reconstructed Proto-Indo-European palatovelars remained distinct and were fricativized, while the labiovelars merged with the 'plain velars'. In the centum languages, the palatovelars merged with the plain velars, while the labiovelars remained distinct. The results of these alternative developments are exemplified by the words for "hundred" in Avestan (''satem'') and Latin (''centum'')—the initial palatovelar developed into a fricative in the former, but became an ordinary velar in the latter. Rather than being a genealogical separation, the centum–satem division is commonly seen as resulting from innovative changes that spread across PIE dialect-branches over a particular geographical area; the centum–satem isogloss intersects a number of other isoglosses that mark distinctions between features in the early IE branches. It may be that the centum branches in fact reflect the original state of affairs in PIE, and only the satem branches shared a set of innovations, which affected all but the peripheral areas of the PIE dialect continuum. Kortlandt proposes that the ancestors of Balts and Slavs took part in satemization before being drawn later into the western Indo-European sphere.


Proposed external relations

From the very beginning of Indo-European studies, there have been attempts to link the Indo-European languages genealogically to other languages and language families. However, these theories remain highly controversial, and most specialists in Indo-European linguistics are sceptical or agnostic about such proposals. Proposals linking the Indo-European languages with a single language family include: * Indo-Uralic, joining Indo-European with Uralic * Pontic, postulated by John Colarusso, which joins Indo-European with Northwest Caucasian Other proposed families include: * Nostratic, comprising all or some of the Eurasiatic languages and the Kartvelian, Dravidian (or wider, Elamo-Dravidian) and Afroasiatic language families * Eurasiatic, a theory championed by Joseph Greenberg, comprising the Uralic, Altaic and various ' Paleosiberian' families ( Ainu, Yukaghir, Nivkh, Chukotko-Kamchatkan, Eskimo–Aleut) and possibly others Nostratic and Eurasiatic, in turn, have been included in even wider groupings, such as Borean, a language family separately proposed by Harold C. Fleming and Sergei Starostin that encompasses almost all of the world's natural languages with the exception of those native to

, and the Andaman Islands. Objections to such groupings are not based on any theoretical claim about the likely historical existence or nonexistence of such macrofamilies; it is entirely reasonable to suppose that they might have existed. The serious difficulty lies in identifying the details of actual relationships between language families, because it is very hard to find concrete evidence that transcends chance resemblance or is not equally likely explained as being due to borrowing, including '' Wanderwörter'', which can travel very long distances. Because the signal-to-noise ratio in historical linguistics declines over time, at great enough time-depths it becomes open to reasonable doubt that one can even distinguish between signal and noise.


Evolution


Proto-Indo-European

The proposed Proto-Indo-European language (PIE) is the reconstructed common ancestor of the Indo-European languages, spoken by the Proto-Indo-Europeans. From the 1960s, knowledge of Anatolian became certain enough to establish its relationship to PIE. Using the method of internal reconstruction, an earlier stage, called Pre-Proto-Indo-European, has been proposed. PIE was an inflected language, in which the grammatical relationships between words were signaled through inflectional morphemes (usually endings). The roots of PIE are basic morphemes carrying a lexical meaning. By addition of
suffix In linguistics, a suffix is an affix which is placed after the Stem (linguistics), stem of a word. Common examples are case endings, which indicate the grammatical case of nouns, adjectives, and verb endings, which form the Grammatical conjugation ...
es, they form stems, and by addition of endings, these form grammatically inflected words ( nouns or verbs). The reconstructed Indo-European verb system is complex and, like the noun, exhibits a system of ablaut.


Diversification

BMAC in "IE languages c. 1500 BC" is Bactria–Margiana Archaeological Complex The diversification of the parent language into the attested branches of daughter languages is historically unattested. The timeline of the evolution of the various daughter languages, on the other hand, is mostly undisputed, quite regardless of the question of Indo-European origins. Using a mathematical analysis borrowed from evolutionary biology, Donald Ringe and Tandy Warnow propose the following evolutionary tree of Indo-European branches: * Pre- Anatolian (before 3500 BC) * Pre- Tocharian * Pre-Italic and Pre-Celtic (before 2500 BC) * Pre-Armenian and Pre-Greek (after 2500 BC) * Proto- Indo-Iranian (2000 BC) * Pre-Germanic and Pre-Balto-Slavic; proto-Germanic c. 500 BC David Anthony proposes the following sequence: * Pre- Anatolian (4200 BC) * Pre- Tocharian (3700 BC) * Pre-Germanic (3300 BC) * Pre-Italic and Pre-Celtic (3000 BC) * Pre-Armenian (2800 BC) * Pre-Balto-Slavic (2800 BC) * Pre-Greek (2500 BC) * Proto- Indo-Iranian (2200 BC); split between Iranian and Old Indic 1800 BC From 1500 BC the following sequence may be given: * 1500–1000 BC: The Nordic Bronze Age develops pre-Proto-Germanic, and the (pre)- Proto-Celtic Urnfield and Hallstatt cultures emerge in Central Europe, introducing the

Important languages for reconstruction

In reconstructing the history of the Indo-European languages and the form of the

, some languages have been of particular importance. These generally include the ancient Indo-European languages that are both well-attested and documented at an early date, although some languages from later periods are important if they are particularly linguistically conservative (most notably, Lithuanian). Early poetry is of special significance because of the rigid poetic meter normally employed, which makes it possible to reconstruct a number of features (e.g. vowel length) that were either unwritten or corrupted in the process of transmission down to the earliest extant written manuscripts. Most noticeable of all: * Vedic Sanskrit (c. 1500–500 BC). This language is unique in that its source documents were all composed orally, and were passed down through

This is the earliest-recorded of all Indo-European languages, and highly divergent from the others due to the early separation of the Anatolian languages from the remainder. It possesses some highly archaic features found only fragmentarily, if at all, in other languages. At the same time, however, it appears to have undergone many early phonological and grammatical changes which, combined with the ambiguities of its writing system, hinder its usefulness somewhat.

Sound changes

As the Proto-Indo-European (PIE) language broke up, its sound system diverged as well, changing according to various sound laws evidenced in the daughter languages. PIE is normally reconstructed with a complex system of 15 stop consonants, including an unusual three-way phonation ( voicing) distinction between voiceless, voiced and " voiced aspirated" (i.e. breathy voiced) stops, and a three-way distinction among velar consonants (''k''-type sounds) between "palatal" ''ḱ ǵ ǵh'', "plain velar" ''k g gh'' and labiovelar ''kʷ gʷ gʷh''. (The correctness of the terms ''palatal'' and ''plain velar'' is disputed; see Proto-Indo-European phonology.) All daughter languages have reduced the number of distinctions among these sounds, often in divergent ways. As an example, in English, one of the Germanic languages, the following are some of the major changes that happened: None of the daughter-language families (except possibly Anatolian, particularly Luvian) reflect the plain velar stops differently from the other two series, and there is even a certain amount of dispute whether this series existed at all in PIE. The major distinction between ''centum'' and ''satem'' languages corresponds to the outcome of the PIE plain velars: * The "central" ''satem'' languages ( Indo-Iranian, Balto-Slavic, Albanian, and Armenian) reflect both "plain velar" and labiovelar stops as plain velars, often with secondary palatalization before a front vowel (''e i ē ī''). The "palatal" stops are palatalized and often appear as sibilants (usually but not always distinct from the secondarily palatalized stops). * The "peripheral" ''centum'' languages ( Germanic, Italic, Celtic, Greek, Anatolian and Tocharian) reflect both "palatal" and "plain velar" stops as plain velars, while the labiovelars continue unchanged, often with later reduction into plain labial or velar consonants. The three-way PIE distinction between voiceless, voiced and voiced aspirated stops is considered extremely unusual from the perspective of linguistic typology—particularly in the existence of voiced aspirated stops without a corresponding series of voiceless aspirated stops. None of the various daughter-language families continue it unchanged, with numerous "solutions" to the apparently unstable PIE situation: * The

s preserve the three series unchanged but have evolved a fourth series of voiceless aspirated consonants. * The Iranian languages probably passed through the same stage, subsequently changing the aspirated stops into fricatives. * Greek converted the voiced aspirates into voiceless aspirates. * Italic probably passed through the same stage, but reflects the voiced aspirates as voiceless fricatives, especially ''f'' (or sometimes plain voiced stops in

). * Celtic, Balto-Slavic, Anatolian, and Albanian merge the voiced aspirated into plain voiced stops. * Germanic and Armenian change all three series in a chain shift (e.g. with ''bh b p'' becoming ''b p f'' (known as '' Grimm's law'' in Germanic)). Among the other notable changes affecting consonants are: * The Ruki sound law (''s'' becomes before ''r, u, k, i'') in the '' satem'' languages. * Loss of prevocalic ''p'' in Proto-Celtic. * Development of prevocalic ''s'' to ''h'' in Proto-Greek, with later loss of ''h'' between vowels. * Verner's law in

. * Grassmann's law (dissimilation of aspirates) independently in Proto-Greek and Proto-Indo-Iranian. The following table shows the basic outcomes of PIE consonants in some of the most important daughter languages for the purposes of reconstruction.

Comparison of conjugations

The following table presents a comparison of conjugations of the thematic present indicative of the verbal root * of the English verb '' to bear'' and its reflexes in various early attested IE languages and their modern descendants or relatives, showing that all languages had in the early stage an inflectional verb system. While similarities are still visible between the modern descendants and relatives of these ancient languages, the differences have increased over time. Some IE languages have moved from synthetic verb systems to largely periphrastic systems. In addition, the
pronoun In linguistics and grammar, a pronoun (list of glossing abbreviations, abbreviated ) is a word or a group of words that one may substitute for a noun or noun phrase. Pronouns have traditionally been regarded as one of the part of speech, parts o ...
s of periphrastic forms are in parentheses when they appear. Some of these verbs have undergone a change in meaning as well. * In Modern Irish ''beir'' usually only carries the meaning ''to bear'' in the sense of bearing a child; its common meanings are ''to catch, grab''. Apart from the first person, the forms given in the table above are dialectical or obsolete. The second and third person forms are typically instead conjugated periphrastically by adding a pronoun after the verb: ''beireann tú, beireann sé/sí, beireann sibh, beireann siad''. * The Hindustani ( Hindi and Urdu) verb ''bʰarnā'', the continuation of the Sanskrit verb, can have a variety of meanings, but the most common is "to fill". The forms given in the table, although etymologically derived from the present indicative, now have the meaning of future subjunctive. The loss of the present indicative in Hindustani is roughly compensated by the periphrastic habitual indicative construction, using the habitual participle (etymologically from the Sanskrit present participle ''bʰarant-'') and an auxiliary: ''ma͠i bʰartā hū̃, tū bʰartā hai, vah bʰartā hai, ham bʰarte ha͠i, tum bʰarte ho, ve bʰarte ha͠i'' (masculine forms). * German is not directly descended from Gothic, but the Gothic forms are a close approximation of what the early West Germanic forms of c. 400 AD would have looked like. The descendant of Proto-Germanic ''*beraną'' (English ''bear'') survives in German only in the compound ''gebären'', meaning "bear (a child)". * The Latin verb ''ferre'' is irregular, and not a good representative of a normal thematic verb. In most Romance languages such as Portuguese, other verbs now mean "to carry" (e.g. Pt. ''portar'' < Lat. ''portare'') and ''ferre'' was borrowed and nativized only in compounds such as "to suffer" (from Latin ''sub-'' and ''ferre'') and "to confer" (from Latin "con-" and "ferre"). * In Modern Greek, ''phero'' φέρω (modern transliteration ''fero'') "to bear" is still used but only in specific contexts and is most common in such compounds as αναφέρω, διαφέρω, εισφέρω, εκφέρω, καταφέρω, προφέρω, προαναφέρω, προσφέρω etc. The form that is (very) common today is ''pherno'' φέρνω (modern transliteration ''ferno'') meaning "to bring". Additionally, the perfective form of ''pherno'' (used for the subjunctive voice and also for the future tense) is also ''phero''. * The dual forms are archaic in standard Lithuanian, and are only presently used in some dialects (e.g. Samogitian). * Among modern Slavic languages, only Slovene continues to have a dual number in the standard variety.

Present distribution

Today, Indo-European languages are spoken by billions of native speakers across all inhabited continents, the largest number by far for any recognised language family. Of the 20 languages with the largest numbers of speakers according to ''Ethnologue'', 10 are Indo-European: English, Hindustani, Spanish, Bengali, French, Russian, Portuguese, German, Persian and Punjabi, each with 100 million speakers or more. Additionally, hundreds of millions of persons worldwide study Indo-European languages as secondary or tertiary languages, including in cultures which have completely different language families and historical backgrounds—there are around 600 million learners of English alone. The success of the language family, including the large number of speakers and the vast portions of the Earth that they inhabit, is due to several factors. The ancient

By the medieval period, only the Semitic, Dravidian, Caucasian, and Uralic languages, and the language isolate Basque remained of the (relatively) indigenous languages of Europe and the western half of Asia. Despite medieval invasions by Eurasian nomads, a group to which the Proto-Indo-Europeans had once belonged, Indo-European expansion reached another peak in the early modern period with the dramatic increase in the population of the Indian subcontinent and European expansionism throughout the globe during the Age of Discovery, as well as the continued replacement and assimilation of surrounding non-Indo-European languages and peoples due to increased state centralization and nationalism. These trends compounded throughout the modern period due to the general global population growth and the results of European colonization of the Western Hemisphere and

Due to colonization and the modern dominance of Indo-European languages in the fields of politics, global science, technology, education, finance, and sports, even many modern countries whose populations largely speak non-Indo-European languages have Indo-European languages as official languages, and the majority of the global population speaks at least one Indo-European language. The overwhelming majority of languages used on the Internet are Indo-European, with English continuing to lead the group; English in general has in many respects become the ''lingua franca'' of global communication.
