Morphology

denticle = dent (semi-transparent) = dent + icle

The root 'dent' is recognizable, but the suffix '-icle' is a Latin diminutive uncommon in everyday English, so the precise sense 'small tooth-like projection' may not be fully guessable for average learners.

Etymology

Denticle comes from the Latin root dent meaning 'tooth' and the small ending -icle meaning 'small'. So a denticle is a 'small tooth', which helps you remember it as a tiny, pointed bump on the outer shell of an insect or spider.
