Morphology

pyrethroid = pyrethrin (semi-transparent) = pyrethr + oid

The adjectival meaning 'relating to or containing pyrethroids' follows from 'pyrethrin' + '-oid', but the root is technical, so average learners may not infer it.

Etymology

The adjective pyrethroid comes from pyrethrum and the ending -oid, which means 'like'. That's why something called pyrethroid contains or is treated with chemicals 'like' the natural pyrethrum insect killer.
