Alphabet
An alphabet is a standard set of letter (alphabet), letters written to represent particular sounds in a spoken language. Specifically, letters largely correspond to phonemes as the smallest sound segments that can distinguish one word from another in a given language. Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables, while logographies assign symbols to words, morphemes, or other semantic units. The first letters were invented in Ancient Egypt to serve as an aid in writing Egyptian hieroglyphs; these are referred to as Egyptian uniliteral signs by lexicographers. This system was used until the 5th century AD, and fundamentally differed by adding pronunciation hints to existing hieroglyphs that had previously carried no pronunciation information. Later on, these phonemic symbols also became used to transcribe foreign words. The first fully phonemic script was the Proto-Sinaitic script, also descending from Egyptian hi ...

🅰
The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes (red blood cells). For human blood transfusions, it is the most important of the 47 different blood type (or group) classification systems currently recognized by the International Society of Blood Transfusions (ISBT) as of December 2022. A mismatch in this serotype (or in various others) can cause a potentially fatal Blood transfusion#Adverse effects, adverse reaction after a transfusion, or an Organ rejection, unwanted immune response to an organ transplant. Such mismatches are rare in modern medicine. The associated anti-A and anti-B antibodies are usually IgM antibodies, produced in the first years of life by sensitization to environmental substances such as food, bacteria, and viruses. The ABO blood types were discovered by Karl Landsteiner in 1901; he received the Nobel Prize in Physiology or Medicine in 1930 for this discovery. ABO blood types are ...

Latin Script
The Latin script, also known as the Roman script, is a writing system based on the letters of the classical Latin alphabet, derived from a form of the Greek alphabet which was in use in the ancient Greek city of Cumae in Magna Graecia. The Greek alphabet was altered by the Etruscan civilization, Etruscans, and subsequently their alphabet was altered by the Ancient Romans. Several Latin-script alphabets exist, which differ in graphemes, collation and phonetic values from the classical Latin alphabet. The Latin script is the basis of the International Phonetic Alphabet (IPA), and the 26 most widespread letters are the letters contained in the ISO basic Latin alphabet, which are the same letters as the English alphabet. Latin script is the basis for the largest number of alphabets of any writing system and is the List of writing systems by adoption, most widely adopted writing system in the world. Latin script is used as the standard method of writing the languages of Western and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleph
Aleph (or alef or alif, transliterated ʾ) is the first Letter (alphabet), letter of the Semitic abjads, including Phoenician alphabet, Phoenician ''ʾālep'' 𐤀, Hebrew alphabet, Hebrew ''ʾālef'' , Aramaic alphabet, Aramaic ''ʾālap'' 𐡀, Syriac alphabet, Syriac ''ʾālap̄'' ܐ, Arabic alphabet, Arabic ''ʾalif'' , and Ancient North Arabian, North Arabian 𐪑. It also appears as Ancient South Arabian script, South Arabian 𐩱 and Ge'ez script, Ge'ez ''ʾälef'' አ. These letters are believed to have derived from an Egyptian hieroglyph depicting an ox's head to Acrophony, describe the initial sound of ''*ʾalp'', the West Semitic languages, West Semitic word for ox (compare Biblical Hebrew ''ʾelef'', "ox"). The Phoenician variant gave rise to the Alpha (letter), Greek alpha (), being re-interpreted to express not the glottal consonant but the accompanying vowel, and hence the A, Latin A and A (Cyrillic), Cyrillic А and possibly the Armenian letter Ayb (Armenian le ...

Open Syllable
A syllable is a basic unit of organization within a sequence of Phone (phonetics), speech sounds, such as within a word, typically defined by linguists as a ''nucleus'' (most often a vowel) with optional sounds before or after that nucleus (''margins'', which are most often consonants). In phonology and studies of languages, syllables are often considered the "building blocks" of words. They can influence the Isochrony, rhythm of a language, its prosody (linguistics), prosody, its Metre (poetry), poetic metre; properties such as stress (linguistics), stress, Tone (linguistics), tone and reduplication operate on syllables and their parts. Speech can usually be divided up into a whole number of syllables: for example, the word ''ignite'' is made of two syllables: ''ig'' and ''nite''. Most languages of the world use relatively simple syllable structures that often alternate between vowels and consonants. Despite being present in virtually all human languages, syllables still have no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indefinite Article
In grammar, an article is any member of a class of dedicated words that are used with noun phrases to mark the identifiability of the referents of the noun phrases. The category of articles constitutes a part of speech. In English, both "the" and "a(n)" are articles, which combine with nouns to form noun phrases. Articles typically specify the grammatical definiteness of the noun phrase, but in many languages, they carry additional grammatical information such as gender, number, and case. Articles are part of a broader category called determiners, which also include demonstratives, possessive determiners, and quantifiers. In linguistic interlinear glossing, articles are abbreviated as . Types of article Definite article A definite article is an article that marks a definite noun phrase. Definite articles, such as the English '' the,'' are used to refer to a particular member of a group. It may be something that the speaker has already mentioned, or it may be ...

English Articles
The articles in English are the definite article '' the'' and the indefinite articles '' a'' and ''an''. They are the two most common determiners. The definite article is the default determiner when the speaker believes that the listener knows the identity of a common noun's referent (because it is obvious, because it is common knowledge, or because it was mentioned in the same sentence or an earlier sentence). The indefinite article is the default determiner for other singular, countable, common nouns, while no determiner is the default for other common nouns. Other determiners are used to add semantic information such as amount (''many'', ''a few''), proximity (''this'', ''those''), or possession (''my'', ''the government's''). Usage English grammar requires that, in most cases, a singular, countable noun phrase start with a determiner. For example, ''I have a box'' is grammatically correct, but *''I have box'' is not. The most common determiners are the articles '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italic Type
In typography, italic type is a cursive font based on a stylised form of calligraphic handwriting. Along with blackletter and roman type, it served as one of the major typefaces in the history of Western typography. Owing to the influence from calligraphy, italics normally slant slightly to the right, ''like so''. Different glyph shapes from roman type are usually usedanother influence from calligraphyand upper-case letters may have Swash (typography), swashes, flourishes inspired by ornate calligraphy. Historically, italics were a distinct style of type used entirely separately from roman type, but they have come to be used in conjunction—most fonts now come with a roman type and an oblique type, oblique version (generally called "italic" though often not true italics). In this usage, italics are a way to emphasise key points in a printed text, to identify many types of creative works, to cite foreign words or phrases, or, when quoting a speaker, a way to show which w ...

Uppercase
Letter case is the distinction between the letters that are in larger uppercase or capitals (more formally ''#Majuscule, majuscule'') and smaller lowercase (more formally ''#Minuscule, minuscule'') in the written representation of certain languages. The writing systems that distinguish between the upper- and lowercase have two parallel sets of letters: each in the majuscule set has a counterpart in the minuscule set. Some counterpart letters have the same shape, and differ only in size (e.g. ), but for others the shapes are different (e.g., ). The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are typically treated identically when sorting in alphabetical order. Letter case is generally applied in a mixed-case fashion, with both upper and lowercase letters appearing in a given piece of text for legibility. The choice of case is often denoted by the grammar of a language or by the conventions of a particular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha
Alpha (uppercase , lowercase ) is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter ''aleph'' , whose name comes from the West Semitic word for ' ox'. Letters that arose from alpha include the Latin letter and the Cyrillic letter . Uses Greek In Ancient Greek, alpha was pronounced and could be either phonemically long ( ː or short ( . Where there is ambiguity, long and short alpha are sometimes written with a macron and breve today: . * = ' "a time" * = ' "tongue" In Modern Greek, vowel length has been lost, and all instances of alpha simply represent the open front unrounded vowel . In the polytonic orthography of Greek, alpha, like other vowel letters, can occur with several diacritic marks: any of three accent symbols (), and either of two breathing marks (), as well as combinations of these. It can also combine with the iota subscript (). Greek grammar In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek.

English Alphabet
Modern English is written with a Latin-script alphabet consisting of 26 Letter (alphabet), letters, with each having both uppercase and lowercase forms. The word ''alphabet'' is a Compound (linguistics), compound of ''alpha'' and ''beta'', the names of the first two letters in the Greek alphabet. The earliest Old English writing during the 5th century used a runic alphabet known as the Anglo-Saxon futhorc, futhorc. The Old English Latin alphabet was adopted from the 7th century onward—and over the following centuries, various letters entered and fell out of use. By the 16th century, the present set of 26 letters had largely stabilised: There are 5 vowel letters and 19 consonant letters—as well as Y and W, which may function as either type. Written English has a large number of Digraph (orthography), digraphs, such as , , , , and . Diacritics are generally not used to write native English words, which is unusual among orthographies used to write the languages of Eu ...
