redundancy. English is about 75 per cent redundant. In other words,
about three quarters of English text is "unnecessary." English could
theoretically express the same things with one quarter its present letters
if it were wholly nonredundant.
Anyone who knows English will know the rules of spelling and
grammar and pronunciation that help engender its redundancy, and he
will know these rules prior to the receipt of any new text in the language.
This is almost tautological: it is only the existence of such rules that
makes communication possible. If a hearer interprets "to" to mean
"from," he will not understand very much. If he pronounces a written m
as /v/, a t as /s/, and so on, he will not get through to his listeners.
These redundant elements, these rules, may be considered the invariant
portion of language. They may not be changed without loss of
comprehension. But one may say what he wishes as long as he follows
them
