Surface Forms

hypopyon singular

hypopyons plural

Morphology

hypopyon = hypo + pyon

Although the term is historically built from Greek elements meaning 'under' and 'pus', it is a specialized medical word whose meaning is not recoverable for an average learner from the visible parts.

Etymology

Hypopyon comes from Greek parts hypo- 'under', as in hypothermia, and -pyon 'pus', so it means 'pus under' the front chamber of the eye.
