Morphology

thunderhead = thunder + head (semi-transparent) = thunder + head

While 'thunder' and 'head' are clear components, the specific meteorological meaning of a cloud formation is not immediately obvious.

Etymology

The word thunderhead comes from thunder ('the loud sound from a storm') and head ('top' or 'rounded part'). So, a thunderhead is the big, rounded top of a cloud, the 'head' of a storm that often brings thunder and rain.
