Morphology

homoplasy = plasy (semi-transparent) = homo + plasy

The prefix 'homo-' ('same') is somewhat recognizable but the combining form '-plasy' is technical and unfamiliar to most learners.

Etymology

Homoplasy comes from Greek parts homo- meaning 'same' and -plasy meaning 'form'. That's why scientists use homoplasy for similar traits in different species, like wings in birds and bats, that evolved independently and are not from a common ancestor.
