catch on

No object

This verb takes no object at all.

How to say it

Stress the particle, not the verb: catch ON. Saying “CATCH on” is the clearest learner tell — the verb stays light and the particle carries the beat.

Link across the gap. The final /tʃ/ of “catch” moves onto the particle and starts its syllable: “catch on” is said “ca-tchon”. Pausing between the words is what makes phrasal verbs sound recited rather than spoken.
