How to say it

Stress the particle, not the verb: break DOWN. Saying “BREAK down” is the clearest learner tell — the verb stays light and the particle carries the beat.

Do not release the /k/. Before the consonant of “down” the stop is held and swallowed rather than popped — the same unreleased-stop move as in hot dog. One smooth unit: “break down”.

Verb vs noun

As a noun the stress flips to the front: the verb is break DOWN, the noun is BREAKDOWN. Same two words, different beat — “to break DOWN” is the action, “a breakdown” is the thing. Getting this backwards makes the sentence land oddly even when every sound is right.
