Morphology

protoconid = proto + conid

The initial proto- is recognizable as 'first', but the second element is a specialized dental combining form, so the meaning is not recoverable from ordinary English morphemes.

Etymology

Protoconid comes from the parts proto- meaning 'first' and conid meaning 'cone' or 'point', so you can remember it as the 'first cone'. That's why the protoconid is the main point or bump on a lower molar tooth that helps an animal chew.
