Morphology

diapedesis = dia + ped + esis

Although 'dia-' means 'through' and '-esis' is a process noun, the central combining form ('ped') is not a recognizable English base here and the term is a technical Greek-derived medical noun, so learners cannot reliably derive the meaning.

Etymology

Diapedesis comes from Greek parts: dia- meaning 'through' and a second part meaning 'to pass'. So it literally means cells 'passing through' the wall of a small blood vessel into nearby tissue, which is exactly what the term describes.
