Morphology

catch + some + z's

The phrase uses "Z's" as an informal/onowomatopoetic convention for snoring or sleep, which is not a standard lexical meaning a learner would know from the written constituents. Knowing 'catch' and 'some' does not let a B1 learner derive 'to sleep' without prior exposure to this cultural/idiomatic convention, so the expression is non-compositional for most learners.

Etymology

Catch some z's comes from old cartoons and comics where a sleeping person is shown with Z's above their head to mean snoring. The verb catch makes the picture of getting or 'catching' those Z's, so the phrase means 'to sleep' or 'take a nap'.
