Morphology

petechia = petech + ia

The element '-ia' is a medical noun-forming suffix but the root 'petech' is not a recognizable English base, so learners cannot derive the meaning from the parts.

Etymology

Petechia comes from the Italian word petecchia, which means 'small spot'. These tiny red or purple 'spots' appear when very small blood vessels break, so the origin explains why we use petechia for those little marks on the skin.
