Synonym discussion

Sense: noun/1

Collision is the most neutral and formal of these terms, common in police reports, insurance claims, and news bulletins. A crash is a collision that produces loud noise and visible destruction — 'car crash' is the everyday word familiar to A2 learners. Accident is the broadest term, covering any unintended harmful event from a broken plate to a multi-vehicle pileup. Impact zooms in on the instant of contact, often used when measuring force (as in 'impact speed'). Smash implies deliberate or extremely violent force, as in 'a car smash' (British informal) or 'a smash-up'. Use collision when you need a precise, formal word; use crash for ordinary conversation; use accident when the focus is on the unintended nature rather than the mechanics of the event.

Etymology

LatinFrenchEnglish

Collision comes from the Latin noun collisio (a striking together), formed from the verb collidere — com- (together) + laedere (to strike, to injure). It entered English in the early 1400s through French (collision). The literal sense of vehicles hitting each other has been in use since the 1500s; the metaphorical meaning (conflict of ideas or interests) appeared in the late 1700s.
