look out
No objectThis verb takes no object at all.
How to say it
Stress the particle, not the verb: look OUT. Saying “LOOK out” is the clearest learner tell — the verb stays light and the particle carries the beat.
Link across the gap. The final /k/ of “look” moves onto the particle and starts its syllable: “look out” is said “loo-kout”. Pausing between the words is what makes phrasal verbs sound recited rather than spoken.
Verb vs noun
As a noun the stress flips to the front: the verb is look OUT, the noun is LOOKOUT. Same two words, different beat — “to look OUT” is the action, “a lookout” is the thing. Getting this backwards makes the sentence land oddly even when every sound is right.
What it means
