There is always the danger that the use of traditional grammatical terms with reference to a wide variety of languages may be taken to imply a secret belief in universal grammar. Every analysis of a particular ‘language’ must of necessity determine the values of the ad hoc categories to which traditional names are given. What is here being sketched is a general linguistic theory applicable to particular linguistic descriptions, not a theory of universals for general linguistic description.
In English we have noticed twenty-five consonant and about twenty vowel phonemes. Although individual pronunciations may differ, the phonemic habits of the same group or class will be similar. They will make similar use of heterophony. Words not phonetically separated — that is, homophones — may be separated by function or by experiential context
Meaning… is to be regarded as a complex of contextual relations, and phonetics, grammar, lexicography, and semantics each handles its own components of the complex in its appropriate context.
