Morphology

rocket + scientist

The literal meaning — a scientist who works on rockets — is directly compositional from 'rocket' + 'scientist', so learners will grasp that basic sense. However, the common idiomatic use (e.g. "you don't need to be a rocket scientist") extends this to mean 'very intelligent' or 'requires special expertise' in a metaphorical/ironic way, which is not fully predictable from the parts and may require exposure to the idiom.

Etymology

Rocket scientist uses the image of a rocket and a scientist to show very high skill, because building rockets looks very hard. So when people say 'you don't have to be a rocket scientist', they mean 'you don't need to be very clever' or that something is not difficult.
