noun-like use after 'a loud'

Common collocations
  • a loud bam
  • bam, bam, bam
Synonyms
  • bang

    more common; covers explosions and louder hits

  • boom

    deeper, longer sound, often from explosions or thunder

  • whack

    suggests a sharp slap or strike, less like a gunshot

Usage Note

Often written with an exclamation mark and placed at the start of a sentence, just before describing what made the noise. Distinguish from sense 2, which marks suddenness rather than the actual sound.

Common Mistakes

The door closed bam.
Bam! The door closed.
'bam' usually comes before the action, not after, when it imitates the noise.

2.exclamation
Definition

Common collocations
  • and bam
  • and then bam
Synonyms
  • suddenly

    neutral and works in formal writing; 'bam' is informal only

  • boom

    very similar use; slightly more triumphant tone

  • just like that

    phrase with the same meaning, common in speech

Antonyms
  • gradually

    opposite idea — over time, not in one moment

Usage Note

Almost always preceded by 'and' and followed by a comma, then a short clause naming what happened. Distinguish from sense 1: this sense does not stand for any real noise.

Common Mistakes

Bam the train arrived.
And bam, the train arrived.
for the 'suddenly' meaning, speakers usually start with 'and' and add a comma after 'bam'.

bam — noun

Synonym discussion

Sense: noun/1

All five words name a sudden noise, but they differ in pitch, length, and how common they are. 'Bang' is the everyday choice and works for almost any sharp loud sound, from a door to a gunshot. 'Bam' is more informal and slightly more cartoon-like; people often write it in comics or shout it for dramatic effect. 'Boom' suggests a deeper, longer sound — thunder, a big explosion, or fireworks heard from far away. 'Thud' is duller and softer, the noise of a heavy bag landing on a carpet. 'Crash' lasts longer and suggests breaking, like plates falling off a shelf. So you might say: a door slams with a bang, a balloon pops with a bam, thunder rolls with a boom, a book lands on a rug with a thud, and a tray of glasses falls with a crash.

Etymology

English (imitative)

First recorded in English in the early 1900s as a way to spell out a sharp, sudden noise. Like 'bang' and 'boom', it is an imitative or 'echoic' word — the sound of saying it copies the sound it describes. The exclamation came first, used in comics and spoken stories, and the noun use ('a loud bam') grew out of that.
