The most important point that can be made from the discussion of mechanisms of semantic change is that context is all‑important. Everything that happens to the meaning of a gram happens because of the contexts in which it is used. It is the use of language in context that shapes the meaning of grammatical morphemes. Thus a true understanding of the mechanisms of change that create grammatical meaning must proceed from analyses of the use of grams as these changes are taking place. The high frequency of grams is also due to the use of grams in environments where their contribution is actually redundant. That is, grams come to be used not just where the meanings they supply are strictly necessary, but also any time that meaning is compatible with the general context and the speaker’s intentions.
