Morphology

H-bomb = H + bomb (semi-transparent) = H + bomb

The word combines 'H' (hydrogen) and 'bomb' transparently for those who know the chemical symbol 'H'; learners who do not know that connection may find it opaque.

Etymology

The word H-bomb comes from the letter H, short for 'hydrogen', and the word bomb. So an H-bomb is a very powerful bomb that uses hydrogen to make a much larger explosion than older nuclear bombs.
