Morphology

somniferous = somnifer (opaque) = somni + fer + ous

The adjective is built on classical elements meaning 'sleep' and 'bearing', but these parts are not transparent to an average English learner.

Etymology

Somniferous comes from two Latin parts: somni- from 'somnus' meaning 'sleep' and -ferous meaning 'bearing' or 'carrying', like in transfer ('to carry across'). So, something somniferous literally 'carries sleep', which is why it means 'causing sleep' today.
