Morphology

time + bomb

The compound 'time bomb' combines the literal nouns 'time' and 'bomb' to suggest something that will 'explode' or become dangerous after a period — a metaphorical extension that many learners can plausibly infer from the parts. However, the shift from a literal explosive device to an abstract future problem requires figurative inference, so the relation is partially but not fully transparent to a B1 learner.

Etymology

Time bomb used for problems comes from the image of a real time bomb with a clock slowly counting down. A problem that quietly gets worse and may suddenly become very dangerous is like that ticking bomb, so we call it 'a serious problem that will become dangerous in the future'.
