Synonym discussion
Sense: noun/1
These words all refer to what someone does about a problem, but they differ in scope, register, and framing. 'Action' is the everyday cover term and is usually uncountable when it means dealing with a situation ('take action on bullying'). 'Measures' is more formal, almost always plural, and points to organised official steps ('emergency measures', 'safety measures'). 'Step' is countable and singles out one piece in a sequence ('the first step is to listen'). 'Intervention' suggests stepping in to stop something already going wrong, often by an outsider — a teacher, doctor, or government. 'Response' frames what is done as a reaction to something that already happened, not a fresh initiative. Compare: 'The mayor took action on pollution' (broad effort) vs. 'The mayor announced new measures to cut pollution' (formal package) vs. 'Closing the factory was an immediate response to the leak'.

Etymology
Borrowed into Middle English in the 1300s from Old French 'accion' (a doing, a deed; also a lawsuit), which in turn came from Latin 'actio', the noun built from 'agere' meaning 'to do, drive, lead'. The same Latin root gave English 'agent', 'act', and 'agenda'. Early English uses kept the Latin range — both 'a thing done' and 'a legal proceeding' — and over the centuries the word fanned out into today's senses, from physical movement to film genre. The verb 'to action' (sense: to carry out a request) is much newer, appearing in twentieth-century business English by treating the noun as a verb.
