The superlative form of 'apt,' meaning most suitable, appropriate, or likely to do something.
From Old French 'apte' (suited), from Latin 'aptus' (fitted). The superlative form '-est' was added following Germanic language conventions for forming the highest degree of adjectives.
The word 'apt' comes from the same root as 'adapt,' which makes sense—an apt response is one that adapts perfectly to the situation!
