Morphology

reaction + time

The meaning 'the amount of time between a stimulus and a response' is directly and compositionally derived from 'reaction' (a response) + 'time' (a duration); the compound simply names the duration of a reaction. This is a common, cross-linguistic noun–noun composition following standard lexical patterns, so a B1 learner who knows both words will likely infer the meaning.

Etymology

Reaction time comes from a simple image: imagine a runner waiting for the start gun, and the time between the sound and their first move is the reaction time. Here reaction is the 'respond' part and time is the 'gap'. So it means the 'amount of time' you need to 'respond' to something.
