Morphology

dorsiflex = flex (semi-transparent) = dorsi + flex + dorsi

The combining form 'dorsi-' ('back') plus 'flex' ('bend') composes the meaning, but 'dorsi-' is a specialized medical combining form unfamiliar to many learners.

Etymology

Dorsiflex comes from the parts dorsi meaning 'back' and flex meaning 'bend', and you can think of flex like when you flex your arm. So to dorsiflex is to bend your foot upward toward the back of the body, which is exactly the movement therapists ask you to make.
