Morphology

cyanuric + acid

The modifier 'cyanuric' is a low-frequency, technical form that a B1 learner is unlikely to know, so knowing 'acid' would only suggest a chemical substance but not the specific stabilizer meaning. The term's specific, technical referent is not derivable from its parts for general learners, so it is not compositional or predictable.

Etymology

Cyanuric acid has the parts cyan (a word for 'blue') and acid, so you can picture a blue shield in the pool. People use this 'blue shield' to 'stabilize' chlorine by protecting it from the sun, so the name helps you remember its job.
