Morphology

occlude = oc + clude

Formally built from the prefix oc- (variant of ob-) + the combining form -clude, so the meaning 'to close/stop' is recoverable for learners familiar with include/exclude but the parts are not standalone common words, making it only partly transparent.

Etymology

Occlude comes from Latin parts ob- meaning 'against' and claudere meaning 'to close', the same root as the English word close. Think of it as 'close against', so to occlude is to block or shut a passage, like a plug that stops water or air.
