lysosome singular

Morphology

lysosome = lyso + some

Formed from bound Greek combining forms (lyso- + -some) that are not recognizable as standalone English words, so an average B1 learner cannot derive the meaning from familiar English components.

Etymology

The word lysosome comes from the Greek parts lysis 'breaking' and soma 'body', and you can see lysis in the common word analysis, where it means 'breaking down'. So a lysosome is a small part of a cell that breaks down waste and old cell parts.
