Common Mistakes

Blast can mean “a lot of fun,” but that is different from the explosion meaning.
Blast is not always a synonym of boom; boom is more often a sound or rise in activity, not the main everyday sense of blast.
Blast is not simply the same as blow in every context; blow only fits the air-current sense.
