What writing mean

Writing, method of human intercommunication by means of arbitrary visual marks forming a system. Writing can be achieved in either limited or full systems, a full system being one that is capable of expressing unambiguously any concept that can be formulated in language.
The separation of the consonant sounds from the vowel sounds, and the separate writing of each. This requires a few more signs but eliminates the ambiguity of having the reader supply the vowels. Alphabetic writing requires the greatest number of signs for a given utterance, but the number of signs required for the system is small enough so that the signs can still be very simple. Because each sign represents a phoneme, the word that is intended by the writer is spelled out explicitly, and no sounds are required to be supplied by the reader.These systems outline the theory and methods of writing, but in actual fact writing systems do not exist in these pure forms. Elements from one type of system are almost always found incorporated in another; an example is the number of logograms used with the modern alphabetic writing system.

Writing systems always tended to be conservative, their origins often being attributed to divine sources. Any change or modification was met with great hesitation, and even today, attempts to reform spelling or eliminate inconsistencies in writing conventions meet with strong resistance. Because of this conservatism major innovations in the structure of a writing system usually occurred when one people borrowed a system from another people. The Akkadians, for example, adapted the syllabic portion of the Sumerian logo-syllabic system to their own language, but retained the logograms, and used them regularly as a type of shorthand. When the Hittites borrowed the system from the Akkadians for their own language, they eliminated most of the polyphonous and homophonous syllabic signs and many of the Sumerian logograms, but used a number of Akkadian syllabic spellings as logograms.
