Morphology

incisor = incise (semi-transparent) = incis + or

Formed from the Latinate verb 'incise' + the nominalizing suffix '-or' meaning 'thing that cuts'; the relation to 'cutting' is clear etymologically but the Latinate base and suffix are not fully transparent to average B1 learners.

Etymology

The word incisor comes from Latin parts in- 'into' and caedere 'to cut'. So an incisor is the front tooth that 'cuts into' food, like having tiny scissors in your mouth.
