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 (Robinson, 2003, p. 36).

Writing as a category

Writing, more particularly, refers to two things: writing as a noun, the thing that is written; and writing as a verb, which designates the activity of writing. It refers to the inscription of characters on a medium, thereby forming words, and larger units of language, known as texts. It also refers to the creation of meaning and the information thereby generated. In that regard, linguistics (and related sciences) distinguishes between the written language and the spoken language. The significance of the medium by which meaning and information is conveyed is indicated by the distinction made in the arts and sciences. For example, while public speaking and poetry reading are both types of speech, the former is governed by the rules of rhetoric and the latter by poetics.

A person who composes a message or story in the form of text is generally known as a writer or an author. However, more specific designations exist which are dictated by the particular nature of the text such as that of poet, essayist, novelist, playwright, journalist, and more. A person who transcribes, translates or produces text to deliver a message authored by another person is known as a scribe, typist or typesetter. A person who produces text with emphasis on the aesthetics of glyphs is known as a calligrapher or graphic designer.

Writing is also a distinctly human activity. It has been said that a monkey, randomly typing away on a typewriter (in the days when typewriters replaced the pen or plume as the preferred instrument of writing) could re-create Shakespeare-- but only if it lived long enough (this is known as the infinite monkey theorem). Such writing has been speculatively designated as coincidental. It is also speculated that extra-terrestrial beings exist who may possess knowledge of writing. The fact is that the only known writing is human writing.

Means for recording information

Wells argues that writing has the ability to "put agreements, laws, commandments on record. It made the growth of states larger than the old city states possible. The command of the priest or king and his seal could go far beyond his sight and voice and could survive his death" (Wells in Robinson, 2003, p. 35).

Writing systems

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 sixth category, pictographic, is insufficient to represent language on its own, but often forms the core of logographies.
