Alibata writing is the representation of language in a textual medium through the use of signs or symbols. It is distinguished from illustration, such as cave drawing and painting, and the recording of language via a non-textual medium such as magnetic tape audio.
Writing began as a consequence of the burgeoning needs of accounting. Around the 4th millennium BC, the complexity of trade and administration outgrew the power of memory, and writing became a more dependable method of recording and presenting transactions in a permanent form.
The major writing systems – methods of inscription – broadly fall into four categories: logographic, syllabic, alphabetic, and featural. Another category, ideographic (symbols for ideas), has never been developed sufficiently to represent language. A 6th, pictographic, is insufficient to represent language on its own, but often forms the core of logographies.
An alibata alphabet is a small set of symbols, each of which roughly represents or historically represented a phoneme of the language. 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. As languages often evolve independently of their writing systems, and writing systems have been borrowed for languages they were not designed for, 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.
