Morphology

cleistothecium = cleisto + thecium

A specialised scientific term formed from Greek combining forms ('cleisto-' 'thecium') that are not familiar or productive for average learners, so the meaning cannot be derived from the parts.

Etymology

The word cleistothecium comes from Greek roots cleisto- meaning 'closed' and -thecium meaning 'box' or 'case', and you can remember this by thinking of the English word close. So a cleistothecium is a 'closed case' that holds spores until it breaks down and the spores are released.
