Alphabet

An alphabet is a writing system that uses a standard set of symbols called graphemes – more commonly known as letters – to more or less represent particular sounds in a spoken language. Specifically, these graphemes largely correspond to phonemes, which are 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 were used to transcribe foreign words. The first fully phonemic script was the Proto-Sinaitic script, also descending from Egyptian hieroglyphs, which was later modified to create the Phoenician alphabet. The Phoenician system is considered the first true alphabet and is the ultimate ancestor of many modern scripts, including Arabic, Cyrillic, Greek, Hebrew, Latin, and possibly Brahmic. Peter T. Daniels distinguishes true alphabets—which use letters to represent both consonants and vowels—from both abugidas and abjads, which only need letters for consonants. Abugidas represent them with diacritics added to letters, while abjads generally lack vowel indicators altogether. In this narrower sense, the Greek alphabet was the first true alphabet; it was originally derived from the Phoenician alphabet, which was an abjad. Alphabets usually have a standard ordering for their letters. This makes alphabets a useful tool in collation, as words can be listed in a well-defined order—commonly known as alphabetical order. This also means that letters may be used as a method of "numbering" ordered items. Some systems demonstrate acrophony, a phenomenon where letters have been given names distinct from their pronunciations. Systems with acrophony include Greek, Arabic, Hebrew, and Syriac; systems without include the Latin alphabet.
