> Is there any example where a word changing meaning has left us unable to express something? I imagine it rarely or never leaves us unable to express something at all, but it may leave us unable to express it so succinctly. There are, as far as I know, no exact synonyms for "disinterested", "meticulous" and "phenomenal" in the senses in which they were formerly used. We can still express each of those meanings in other ways, but we need a phrase rather than a single word.
