Ablaut and vowel gradation

Vowel gradation is any vowel difference between two related words (such as ''photograph'' fəʊtəgrɑːfand ''photography'' əˈtɒgrəfi or two forms of the same word (such as ''man'' and ''men''). The difference need not be indicated in the spelling. There are many kinds of vowel gradation in English and other languages, which are discussed generally in the article

), others in vowel coloring (qualitative gradation: ''man'' / ''men'') and others the complete disappearance of a vowel (reduction to zero: ''could not'' → ''couldn't''). For the study of European languages, one of the most important instances of vowel gradation is the Indo-European ablaut, remnants of which can be seen in the English verbs ''ride'', ''rode'', ''ridden'', or ''fly'', ''flew'', ''flown''. For simply learning English grammar, it is enough to note that these verbs are irregular, but understanding why they have unusual forms that seem irregular (and indeed why they are actually perfectly regular within their own terms) requires an understanding of the grammar of the reconstructed proto-language. Ablaut is the oldest and most extensive single source of vowel gradation in the Indo-European languages and must be distinguished clearly from other forms of gradation, which developed later, such as Germanic umlaut (''man'' / ''men'', ''goose'' / ''geese'', ''long'' / ''length'') or the results of modern English word-stress patterns (''man'' / ''woman'', ''photograph'' / ''photography''). Confusingly, in some contexts, the terms 'ablaut', 'vowel gradation', 'apophony' and 'vowel alternation' are used synonymously, especially in

comparisons, but historical linguists prefer to keep 'ablaut' for the specific Indo-European phenomenon, which is the meaning intended by the linguists who first coined the word.


Ablaut grades

In Proto-Indo-European, the basic, inherent vowel of most syllables was a short ''e''. ''Ablaut'' is the name of the process whereby this short ''e'' changed, becoming short ''o'', long ''ē'', long ''ō'' or sometimes disappearing entirely to leave no vowel at all. Thus, ablaut results in the alternation of the following sounds: If a syllable had a short ''e'', it is said to be in the "e-grade" or "full grade". When it had no vowel, it is said to be in the "zero grade". Syllables with long vowels are said to be in "lengthened grade". (When the ''e''-grade or the ''o''-grade is referred to, the short vowel forms are meant.) A classic example of the five grades of ablaut in a single root is provided by the different case forms of two closely related Greek words. In the following table, an acute accent (´) marks the syllable carrying the word stress; a macron (¯) marks long vowels and the syllable in bold is the one illustrating the different vowel gradations. In this unusually neat example, the following can be seen: *A switch to the zero-grade when the word stress moves to the following syllable. *A switch to the o-grade when the word stress moves to the preceding syllable. *A lengthening of the vowel when the syllable is in word-final position before a sonorant. As with most reconstructions, however, scholars differ about the details of this example. One way to think of this system is to suppose that Proto-Indo-European originally had only one vowel, short ''e'', and over time, it changed according to phonetic context, so the language started to develop a more complex vowel system. Thus, it has often been speculated that an original e-grade underwent two changes in some phonetic environments: under certain circumstances, it changed to ''o'' (the o-grade) and in others, it disappeared entirely (the zero-grade). However, that is not certain: the phonetic conditions that controlled ablaut have never been determined, and the position of the word stress may not have been a key factor at all. There are many counterexamples to the proposed rules: ''*deywós'' and its nominative plural ''*deywóes'' show pretonic and posttonic e-grade, respectively, and ''*wĺ̥kʷos'' has an accented zero grade.


Lengthened grades

Many examples of lengthened grades, including those listed above, are not directly conditioned by ablaut. Instead, they are a result of sound changes like
Szemerényi's law Szemerényi's law (or Szemerényi's lengthening) is both a sound change and a synchronic phonological rule that operated during an early stage of the Proto-Indo-European language (PIE). Though its effects are evident in many reconstructed as wel ...

of originally short vowels. In the examples above, Szemerényi's law affected the older sequences *ph2-tér-s and *n̥-péh2-tor-s, changing them to *ph2-tḗr and *n̥-péh2-tōr. Thus, these forms were originally in the regular, unlengthened e-grade and o-grade. Such lengthened vowels were, however, later grammaticalised and spread to other words in which the change did not occur. Nevertheless, there are examples of true lengthened grades, in which short ''e'' alternates with long ''ē''. Examples are the verbs with "Narten" inflection, and nouns like ''*mḗh₁-n̥s'' "moon", genitive ''*méh₁-n̥s-os''. Alternations of this type were rare, however, and the ''e'' ~ ''o'' ~ ''∅'' alternation was the most common by far. The long ''ō'' grade was rarer still and may not have actually been a part of the ablaut system at all.


Zero grade

The zero grade of ''ablaut'' may appear difficult for speakers of English. In the case of *ph2trés, which may already have been pronounced something like , it is not difficult to imagine it as a contraction of an older *ph2terés, pronounced perhaps , as this combination of consonants and vowels would be possible in English as well. In other cases, however, the absence of a vowel strikes the speaker of a modern western European language as unpronounceable. To understand, one must be aware that there were a number of sounds that were consonants in principle but could operate in ways analogous to vowels: the four syllabic sonorants, the three
laryngeals The laryngeal theory is a theory in the historical linguistics of the Indo-European languages positing that: * The Proto-Indo-European language (PIE) had a series of phonemes beyond those reconstructable by the comparative method. That is, the ...
and the two semi-vowels: *The syllabic sonorants are ''m'', ''n'', ''r'' and ''l'', which could be consonants much as they are in English, but they could also be held on as continuants and carry a full syllable stress and then are transcribed with a small circle beneath them. There are many modern languages who show these sounds in syllable nuclei. *The laryngeals could be pronounced as consonants, in which case they were probably variations on the ''h'' sound and so normally transcribed as h1, h2 and h3. However, they could also carry a syllable stress, in which case they were more like vowels. Thus, some linguists prefer to transcribe them ə1, ə2 and ə3. The vocalic pronunciation may have originally involved the consonantal sounds with a very slight schwa before and/or after the consonant. *In pre-vocalic positions, the phonemes ''u'' and ''i'' were semi-vowels, probably pronounced like English ''w'' and ''y'', but they could also become pure vowels when the following ablaut vowel reduced to zero. When ''u'' and ''i'' came in postvocalic positions, the result was a diphthong. Ablaut is nevertheless regular and looks like this: Thus, any of these could replace the ablaut vowel when it was reduced to the zero-grade: the pattern CVrC (for example, ''*bʰergʰ-'') could become CrC (''*bʰr̥gʰ-''). However, not every PIE syllable was capable of forming a zero grade; some consonant structures inhibited it in particular cases, or completely. Thus, for example, although the

syncope in unaccented syllables, but in some cases the lack of accent does not cause zero grade: ''*deywó-'', nominative plural ''*-es'' "god". There does not seem to be a rule governing the unaccented syllables that take zero grade and the ones that take stronger grades.


a-grade

It is still a matter of debate whether PIE had an original a-vowel at all. In later PIE, the disappearance of the laryngeal h2 could leave an a-colouring and this may explain all occurrences of ''a'' in later PIE. However, some argue controversially that the e-grade could sometimes be replaced by an a-grade without the influence of a laryngeal, which might help to explain the vowels in class 6 Germanic verbs, for example.


Subsequent development

Although PIE had only this one, basically regular, ablaut sequence, the development in the daughter languages is frequently far more complicated, and few reflect the original system as neatly as Greek. Various factors, such as
vowel harmony In phonology, vowel harmony is an Assimilation (linguistics), assimilatory process in which the vowels of a given domain – typically a phonological word – have to be members of the same natural class (thus "in harmony"). Vowel harmony is t ...
, assimilation with nasals, or the effect of the presence of laryngeals in the Indo-European (IE) roots as well as their subsequent loss in most daughter languages, mean that a language may have several different vowels representing a single vowel in the parent language. In particular, the zero grade was often subject to modification from changes in the pronunciation of syllabic sonorants. For example, in Germanic, syllabic sonorants acquired an

''-u-'', thus converting the original zero grade to a new "u-grade" in many words. Thus, while ablaut survives in some form in all Indo-European languages, it became progressively less systematic over time. Ablaut explains vowel differences between related words of the same language. For example: * English ''strike'' and ''stroke'' both come from the same IE root ''*streyg-''. The former comes from the e-grade, the latter from the o-grade. * German ''Berg'' (mountain, hill) and ''Burg'' (castle) both come from the root ''*bʰergʰ-'', which presumably meant "high". The former comes from the e-grade, the latter from the zero-grade. (Zero-grade followed by ''r'' becomes ''ur'' in Germanic.) Ablaut also explains vowel differences between cognates in different languages. *English ''tooth'' comes from Germanic ''*tanþ-s'' (e.g. Old English ''tōþ'', Old High German ''zand''), genitive ''*tund-iz'' (Gothic ''tunþus'', but also "thornbush", literally "horse-tooth"). This form is related to Latin ''dens, dentis'' and Greek '', '', with the same meaning, and is reflected in the English words ''dentist'' and ''orthodontic''. One reconstructed IE form is ''*dónts'', genitive ''*dn̥tés''. The consonant differences can be explained by regular sound shifts in primitive Germanic but not the vowel differences: by the regular laws of sound changes, Germanic ''a'' can originate from PIE ''o'', but ''un'' usually goes back to a syllabic ''n̥''. :The explanation is that the Germanic and Greek nominative forms developed from the o-grade, the Latin word and the Germanic genitive from the zero-grade (in which syllabic ''n̥'' developed into ''en'' much in the same way as it became ''un'' in Germanic). Going a step further back, some scholars reconstruct ''*h1dónts'', from the zero grade of the root ''*h1ed-'' 'to eat' and the participle ''-ont-'' and explain it as 'the eating one'. *English ''foot'' comes from the lengthened o-grade of ''*ped-''. Greek '', '' and Latin ''pes, pedis'' (compare English ''octopus'' and ''pedestrian''), come from the (short) o-grade and the e-grade respectively.

Grammatical function

In PIE, there were already ablaut differences within the paradigms of verbs and nouns. These were not the main markers of grammatical form, since the inflection system served this purpose, but they must have been significant secondary markers. An example of ablaut in the paradigm of the noun in PIE can be found in ''*pértus'', from which the English words ''ford'' and (via Latin) ''port'' are derived (both via the zero-grade stem ''*pr̥t-''). An example in a verb is *bʰeydʰ- "to wait" (cf. "bide"). In the daughter languages, these came to be important markers of grammatical distinctions. The vowel change in the Germanic strong verb, for example, is the direct descendant of that seen in the Indo-European verb paradigm. Examples in modern English are the following: It was in this context of Germanic verbs that ''ablaut'' was first described, and this is still what most people primarily associate with the phenomenon. A fuller description of ''ablaut'' operating in English, German and Dutch verbs and of the historical factors governing these can be found at the article

The difference between singular and plural in these languages is easily explained: the PIE root is ''*h1es-''. In the singular, the stem is stressed, so it remains in the e-grade, and it takes the inflection ''-ti''. In the plural, however, the inflection ''-énti'' was stressed, causing the stem to reduce to the zero grade: ''*h1es-énti'' → ''*h1s-énti''. See main article:
