William Caslon, letter founder; from the 1728 "Cyclopaedia".]

An alphabet is a standardized set of "letters"mdash basic written symbolsmdash each of which roughly represents a phoneme, a spoken language, either as it exists now or as it was in the past. There are other systems, such as logographies, in which each character represents a word, morpheme, or semantic unit, and syllabaries, in which each character represents a syllable. Alphabets are classified according to how they indicate vowels:
* the same way as consonants, as in Greek (true alphabet)
* modifications of consonants, as in Hindi (abugida)
* not at all, as in Hebrew (abjad)

The word "alphabet" came into Middle English from the Late Latin word Alphabetum, which in turn originated in the Ancient Greek "Αλφάβητος" Alphabetos, from "alpha" and "beta," the first two letters of the Greek alphabet. [ [ Encyclopædia Britannica Onlinendash Merriam-Webster's Online Dictionary] ] "Alpha" and "beta" in turn came from the first two letters of the Phoenician alphabet, and meant "ox" and "house" respectively. There are dozens of alphabets in use today. Most of them are composed of lines (linear writing); notable exceptions are Braille, fingerspelling, and Morse code.

Linguistic definition and context

The term alphabet prototypically refers to a writing system that has characters (graphemes) for representing both consonant and vowel sounds, even though there may not be a complete one-to-one correspondence between symbol and sound.

A grapheme is an abstract entity which may be physically represented by different styles of glyphs. There are many written entities which do not form part of the alphabet, including numerals, mathematical symbols, and punctuation. Some human languages are commonly written by using a combination of logograms (which represent morphemes or words) and syllabaries (which represent syllables) instead of an alphabet. Egyptian hieroglyphs and Chinese characters are two of the best-known writing systems with predominantly non-alphabetic representations.

Non-written languages may also be represented alphabetically. For example, linguists researching a non-written language (such as some of the indigenous Amerindian languages) will use the International Phonetic Alphabet to enable them to write down the sounds they hear.

Most, if not all, linguistic writing systems have some means for phonetic approximation of foreign words, usually using the native character set.

Middle Eastern Scripts

The history of the alphabet starts in ancient Egypt. By 2700 BC Egyptian writing had a set of some 22 hieroglyphs [cite web |url= |title=The Development of the Western Alphabet |accessdate=2008-08-04 |first=Gnomon |coauthors=Lynn, Bernadette |date=2004-04-08 |work=h2g2 |publisher=BBC] to represent syllables that begin with a single consonant of their language, plus a vowel (or no vowel) to be supplied by the native speaker. These glyphs were used as pronunciation guides for logograms, to write grammatical inflections, and, later, to transcribe loan words and foreign names. [Daniels and Bright (1996), pp. 74–75.]

However, although seemingly alphabetic in nature, the original Egyptian uniliterals were not a system and were never used by themselves to encode Egyptian speech. [Daniels and Bright (1996), pp. 74.] In the Middle Bronze Age an apparently "alphabetic" system known as the Proto-Sinaitic script is thought by some to have been developed in central Egypt around 1700 BC for or by Semitic workers, but only one of these early writings has been deciphered and their exact nature remains open to interpretation.Coulmas (1989), p. 140.] Based on letter appearances and names, it is believed to be based on Egyptian hieroglyphs.

This script eventually developed into the Proto-Canaanite alphabet, which in turn was refined into the Phoenician alphabet. [Daniels and Bright (1996), pp. 92–94.] Note that the scripts mentioned above are not considered proper alphabets, as they all lack characters representing vowels. These early vowelless alphabets are called abjads, and still exist in scripts such as Arabic, Hebrew and Syriac.

Phoenician was the first major phonemic script.Daniels and Bright (1996), pp. 94–96.] [Coulmas (1989), p. 141.] In contrast to two other widely used writing systems at the time, Cuneiform and Egyptian hieroglyphs, each of which contained thousands of different characters, it contained only about two dozen distinct letters, making it a script simple enough for common traders to learn. Another advantage to Phoenician was that it could be used to write down many different languages, since it recorded words phonemically.

The script was spread by the Phoenicians, whose Thalassocracy allowed the script to be spread across the Mediterranean. In Greece, the script was modified to add the vowels, giving rise to the first true alphabet. The Greeks took letters which did not represent sounds that existed in Greek, and changed them to represent the vowels. This marks the creation of a "true" alphabet, with the presence of both vowels and consonants as explicit symbols in a single script. In its early years, there were many variants of the Greek alphabet, a situation which caused many different alphabets to evolve from it.

European alphabets

The Cumae form of the Greek alphabet was carried over to the Italian peninsula by Greek colonists from Euboea, where it gave rise to a variety of alphabets used to inscribe the Italic languages. One of these became the Latin alphabet, which was spread across Europe as the Romans expanded their empire. Even after the fall of the Roman state, the alphabet survived in intellectual and religious works. It eventually became used for the descendant languages of Latin (the Romance languages), and then for the other languages of Europe.

Another notable script is Elder Futhark, which is believed to have evolved out of one of the Old Italic alphabets. Elder Futhark gave rise to a variety of alphabets known collectively as the Runic alphabets. The Runic alphabets were used for Germanic languages from 100 AD to the late Middle Ages. Its usage was mostly restricted to engravings on stone and jewelry, although inscriptions have also been found on bone and wood. These alphabets have since been replaced with the Latin alphabet, except for decorative usage for which the runes remained in use until the 20th century.

The Glagolitic alphabet was the script of the liturgical language Old Church Slavonic, and became the basis of the Cyrillic alphabet. The Cyrillic alphabet is one of the most widely used modern alphabets, and is notable for its use in Slavic languages and languages within the former Soviet Union. Variants include the Serbian, Bulgarian and Russian alphabets. The Glagolitic alphabet is believed to have been created by Saints Cyril and Methodius, while the Cyrillic alphabet was invented by the Bulgarian scholar Clement of Ohrid, who was their disciple. They feature many letters that appear to have been borrowed from or influenced by the Greek alphabet and the Hebrew alphabet.

Asian alphabets

Beyond the logographic Chinese writing, many phonetic scripts are in existence in Asia. The Arabic alphabet, Hebrew alphabet, Syriac alphabet, and other abjads of the Middle East are developments of the Aramaic alphabet, but because these writing systems are largely consonant-based they are often not considered true alphabets.

Most alphabetic scripts of India and Eastern Asia are descended from the Brahmi script, which is often believed to be a descendent of Aramaic, but this link is controversial. These scripts are abugidasmdash that is, they write syllables instead of individual sounds, so their status as alphabets is disputed.

In Korea, the Hangeul alphabet was created, although it may also have been derived from the Mongolian Phagspa script, which in turn was derived from the Brahmi script. Hangeul is a unique alphabet in a variety of ways: it is a featural alphabet, where many of the letters are designed off of a sound's place of articulation; it was consciously designed by the government at the time; and it situates individual letters into syllable clusters with equal dimensions as Chinese characters to allow for mixed script writing.

Zhuyin (sometimes called "Bopomofo") is a semi-syllabary used to phonetically transcribe Mandarin Chinese in the Republic of China. After the later establishment of the People's Republic of China and its adoption of Hanyu Pinyin, the use of Zhuyin in Mainland China today is limited, but it's still widely used in Taiwan where the Republic of China still governs. Zhuyin developed out of a form of Chinese shorthand based on Chinese characters in the early 1900s and has elements of both an alphabet and a syllabary. Like an alphabet the phonemes of syllable initals are represented by individual symbols, but like a syllabary the phonemes of the syllable finals are not; rather, each possible final (excluding the medial glide) is represented by its own symbol. For example, "luan" is represented as ㄌㄨㄢ ("l-u-an"), where the last symbol ㄢ represents the entire final "-an". While Zhuyin is not used as a mainstream writing system, it is still often used in ways similar to a romanization systemmdash that is, for aiding in pronunciation and as an input method for Chinese characters on computers and cell phones. In Japan there is an input system allowing you to type kanji.

European alphabets, especially Latin and Cyrillic, have been adapted for many languages of Asia. Arabic is also widely used, sometimes as an abjad (as with Urdu and Persian) and sometimes as a complete alphabet (as with Kurdish and Uyghur).


The term "alphabet" is used by linguists and paleographers in both a wide and narrow sense. In the wider sense, an alphabet is a script that is "segmental" on the phoneme levelmdash that is, that has separate glyphs for individual sounds and not for larger units such as syllables or words. In the narrower sense, some scholars distinguish "true" alphabets from two other types of segmental script, abjads and abugidas. These three differ from each other in the way they treat vowels: Abjads have letters for consonants and leave most vowels unexpressed; abugidas are also consonant-based, but indicate vowels with diacritics to or a systematic graphic modification of the consonants. In alphabets in the narrow sense, on the other hand, consonants and vowels are written as independent letters. The earliest known alphabet in the wider sense is the Wadi el-Hol script, believed to be an abjad, which through its successor Phoenician is the ancestor of modern alphabets, including Arabic, Greek, Latin (via the Old Italic alphabet), Cyrillic (via the Greek alphabet) and Hebrew (via Aramaic).

Examples of present-day abjads are the Arabic and Hebrew scripts; true alphabets include Latin, Cyrillic, and Korean hangul; and abugidas are used to write Tigrinya Amharic, Hindi, and Thai. The Canadian Aboriginal syllabics are also an abugida rather than a syllabary as their name would imply, since each glyph stands for a consonant which is modified by rotation to represent the following vowel. (In a true syllabary, each consonant-vowel combination would be represented by a separate glyph.)

The boundaries between the three types of segmental scripts are not always clear-cut. For example, Sorani Kurdish is written in the Arabic script, which is normally an abjad. However, in Kurdish, writing the vowels is mandatory, and full letters are used, so the script is a true alphabet. Other languages may use a Semitic abjad with mandatory vowel diacritics, effectively making them abugidas. On the other hand, the Phagspa script of the Mongol Empire was based closely on the Tibetan abugida, but all vowel marks were written after the preceding consonant rather than as diacritic marks. Although short "a" was not written, as in the Indic abugidas, one could argue that the linear arrangement made this a true alphabet. Conversely, the vowel marks of the Tigrinya abugida and the Amharic abugida (ironically, the original source of the term "abugida") have been so completely assimilated into their consonants that the modifications are no longer systematic and have to be learned as a syllabary rather than as a segmental script. Even more extreme, the Pahlavi abjad eventually became logographic. (See below.)

Thus the primary classification of alphabets reflects how they treat vowels. For tonal languages, further classification can be based on their treatment of tone, though names do not yet exist to distinguish the various types. Some alphabets disregard tone entirely, especially when it does not carry a heavy functional load, as in Somali and many other languages of Africa and the Americas. Such scripts are to tone what abjads are to vowels. Most commonly, tones are indicated with diacritics, the way vowels are treated in abugidas. This is the case for Vietnamese (a true alphabet) and Thai (an abugida). In Thai, tone is determined primarily by the choice of consonant, with diacritics for disambiguation. In the Pollard script, an abugida, vowels are indicated by diacritics, but the placement of the diacritic relative to the consonant is modified to indicate the tone. More rarely, a script may have separate letters for tones, as is the case for Hmong and Zhuang. For most of these scripts, regardless of whether letters or diacritics are used, the most common tone is not marked, just as the most common vowel is not marked in Indic abugidas; in Zhuyin not only is one of the tones unmarked, but there is a diacritic to indicate lack of tone, like the virama of Indic.

The number of letters in an alphabet can be quite small. The Book Pahlavi script, an abjad, had only twelve letters at one point, and may have had even fewer later on. Today the Rotokas alphabet has only twelve letters. (The Hawaiian alphabet is sometimes claimed to be as small, but it actually consists of 18 letters, including the ʻokina and five long vowels.) While Rotokas has a small alphabet because it has few phonemes to represent (just eleven), Book Pahlavi was small because many letters had been "conflated"mdash that is, the graphic distinctions had been lost over time, and diacritics were not developed to compensate for this as they were in Arabic, another script that lost many of its distinct letter shapes. For example, a comma-shaped letter represented "g, d, y, k," or "j". However, such apparent simplifications can perversely make a script more complicated. In later Pahlavi papyri, up to half of the remaining graphic distinctions of these twelve letters were lost, and the script could no longer be read as a sequence of letters at all, but instead each word had to be learned as a wholemdash that is, they had become logograms as in Egyptian Demotic.

The largest segmental script is probably an abugida, Devanagari. When written in Devanagari, Vedic Sanskrit has an alphabet of 53 letters, including the "visarga" mark for final aspiration and special letters for "kš" and "jñ," though one of the letters is theoretical and not actually used. The Hindi alphabet must represent both Sanskrit and modern vocabulary, and so has been expanded to 58 with the "khutma" letters (letters with a dot added) to represent sounds from Persian and English.

The largest known abjad is Sindhi, with 51 letters. The largest alphabets in the narrow sense include Kabardian and Abkhaz (for Cyrillic), with 58 and 56 letters, respectively, and Slovak (for the Latin alphabet), with 46. However, these scripts either count di- and tri-graphs as separate letters, as Spanish did with "ch" and "ll" up to a recent time, or uses diacritics like Slovak "č". The largest true alphabet where each letter is graphically independent is probably Georgian, with 41 letters.

Syllabaries typically contain 50 to 400 glyphs (though the Múra-Pirahã language of Brazil would require only 24 if it did not denote tone, and Rotokas would require only 30), and the glyphs of logographic systems typically number from the many hundreds into the thousands. Thus a simple count of the number of distinct symbols is an important clue to the nature of an unknown script.

It is not always clear what constitutes a distinct alphabet. French uses the same basic alphabet as English, but many of the letters can carry additional marks, such as é, à, and ô. In French, these combinations are not considered to be additional letters. However, in Icelandic, the accented letters such as á, í, and ö are considered to be distinct letters of the alphabet. In Spanish, ñ is considered a separate letter, but accented vowels such as á and é are not. double L is also considered a separate letter to a single l. Some adaptations of the Latin alphabet are augmented with ligatures, such as æ in Old English and Ȣ in Algonquian; by borrowings from other alphabets, such as the thorn þ in Old English and Icelandic, which came from the Futhark runes; and by modifying existing letters, such as the eth ð of Old English and Icelandic, which is a modified "d". Other alphabets only use a subset of the Latin alphabet, such as Hawaiian, or Italian, which only uses the letters "j, k, x, y" and "w" in foreign words.

Alphabetic order

It is unknown whether the earliest alphabets had a defined sequence. Some alphabets today, such as Hanunoo, are learned one letter at a time, in no particular order, and are not used for collation where a definite order is required. However, a dozen Ugaritic tablets from the fourteenth century BC preserve the alphabet in two sequences. One, the "ABGDE" order later used in Phoenician, has continued with minor changes in Hebrew, Greek, Armenian, Gothic, Cyrillic, and Latin; the other, "HMĦLQ," was used in southern Arabia and is preserved today in Ethiopic. [Millard, A.R. "The Infancy of the Alphabet", "World Archaeology" 17, No. 3, Early Writing Systems (Feb., 1986): 390–398. page 395.] Both orders have therefore been stable for at least 3000 years.

The historical order was abandoned in Runic and Arabic, although Arabic retains the traditional "abjadi order" for numbering.

The Brahmic family of alphabets used in India use a unique order based on phonology: The letters are arranged according to how and where they are produced in the mouth. This organization is used in Southeast Asia, Tibet, Korean hangul, and even Japanese kana, which is not an alphabet.

The Phoenician letter names, in which each letter is associated with a word that begins with that sound, continue to be used in Samaritan, Aramaic, Syriac, Hebrew, and Greek. However, they were abandoned in Arabic, Cyrillic and Latin.

Orthography and spelling

Each language may establish certain general rules that govern the association between letters and phonemes, but, depending on the language, these rules may or may not be consistently followed. In a perfectly phonological alphabet, the phonemes and letters would correspond perfectly in two directions: a writer could predict the spelling of a word given its pronunciation, and a speaker could predict the pronunciation of a word given its spelling. However, languages often evolve independently of their writing systems, and writing systems have been borrowed for languages they were not designed for, so the degree to which letters of an alphabet correspond to phonemes of a language varies greatly from one language to another and even within a single language.

Languages may fail to achieve a one-to-one correspondence between letters and sounds in any of several ways:

* A language may represent a given phoneme with a combination of letters rather than just a single letter. Two-letter combinations are called digraphs and three-letter groups are called trigraphs. German uses the tesseragraphs (four letters) "tsch" for the phoneme IPA2|tʃ and "dsch" for IPA| [dʒ] , although, the latter is rare. Kabardian also uses a tesseragraph for one of its phonemes.
* A language may represent the same phoneme with two different letters or combinations of letters.
* A language may spell some words with unpronounced letters that exist for historical or other reasons.
* Pronunciation of individual words may change according to the presence of surrounding words in a sentence (sandhi).
* Different dialects of a language may use different phonemes for the same word.
* A language may use different sets of symbols or different rules for distinct sets of vocabulary items, such as the Japanese hiragana and katakana syllabaries, or the various rules in English for spelling words from Latin and Greek, or the original Germanic vocabulary.

National languages generally elect to address the problem of dialects by simply associating the alphabet with the national standard. However, with an international language with wide variations in its dialects, such as English, it would be impossible to represent the language in all its variations with a single phonetic alphabet.

Some national languages like Finnish, Turkish and Bulgarian have a very regular spelling system with a nearly one-to-one correspondence between letters and phonemes. Strictly speaking, there is no word in the Finnish, Turkish and Bulgarian languages corresponding to the verb "to spell" (meaning to split a word into its letters), the closest match being a verb meaning to split a word into its syllables. Similarly, the Italian verb corresponding to 'spell', "compitare", is unknown to many Italians because the act of spelling itself is almost never needed: each phoneme of Standard Italian is represented in only one way. However, pronunciation cannot always be predicted from spelling in cases of irregular syllabic stress. In standard Spanish, it is possible to tell the pronunciation of a word from its spelling, but not vice versa; this is because certain phonemes can be represented in more than one way, but a given letter is consistently pronounced. French, with its silent letters and its heavy use of nasal vowels and elision, may seem to lack much correspondence between spelling and pronunciation, but its rules on pronunciation are actually consistent and predictable with a fair degree of accuracy.

At the other extreme, however, are languages such as English, where the spelling of many words simply has to be memorized as they do not correspond to sounds in a consistent way. For English, this is because the Great Vowel Shift occurred after the orthography was established, and because English has acquired a large number of loanwords at different times retaining their original spelling at varying levels. However, even English has general, albeit complex, rules that predict pronunciation from spelling, and these rules are successful most of the time. Rules to predict spelling from the pronunciation have a high failure rate for English.

Sometimes, countries have the written language undergo a spelling reform in order to realign the writing with the contemporary spoken language. These can range from simple spelling changes and word forms to switching the entire writing system itself, as when Turkey switched from the Arabic alphabet to the Roman alphabet.

The sounds of speech of all languages of the world can be written by a rather small universal phonetic alphabet. A standard for this is the International Phonetic Alphabet.
