Synonym discussion

Sense: verb/1

For loud impact noises, these words overlap but point to different pictures. 'Bang' is the broad everyday choice for one hard sharp noise or for making something produce it: a door bangs, pipes bang, someone bangs a pan down. 'Slam' is narrower and is especially natural for doors, lids, and other things closing hard. 'Crash' usually suggests a bigger, more destructive event, often with things breaking or falling. 'Clatter' is different again: it points to repeated hard sounds from light objects such as dishes, tools, or wheels. So a student might bang a locker shut, a truck might crash into a wall, and plates might clatter across the kitchen floor.

Etymology

Imitative soundEnglish

'Bang' began in English as an imitative word for a short heavy noise, like the sound of a blow, a shot, or a door slamming. Because it started as a sound word, English later used it not only for the noise itself, but also for the action that causes the noise, for a hard hit, and for fixed expressions such as 'go bang'.
