Quine/Millikan: is right when he speaks of a "variety of connections" between words and experience. Even members of the same linguistic community are "differently trimmed bushes".
Millikan: Problem: what is then "the" Intension?
Inner expression/Millikan: e.g. "red" here everyone must have an inner term that corresponds to "red".
Definition language-bound intensions/terminology/Millikan: be the volatile (acquired) intensions that one must have in order to have a word in its idiolect. These must be public.
N.B.: language-bound intensions never correspond to synonyms e.g. "rot" - "red".
