Morphology

pyrrolidone = pyrrolid + one

This is a specialized chemical formation (combining form + nomenclatural suffix) whose components are not recognizable English words for most learners, making the compound opaque.

Etymology

Pyrrolidone is built from pyrrole ('five-membered ring') and -one ('oxygen double-bond'), so the name literally points to a five-sided ring with a special oxygen group. That is why a pyrrolidone ring is a common structure found in many medicines and other organic compounds.
