for
/fɔr/10 verbsA target, a purpose, or a substitution.
FOR marks the thing you want or seek: look for, ask for, wait for, hope for. It is almost always inseparable — the object cannot come between the verb and FOR.
A distinct sense is deception: fall for something means you were taken in by it.
What it does to the sound
FOR is a function word and reduces to /fɚ/ in connected speech — look for it is “loo-kfrit”. Giving it a full /ɔr/ vowel is a reliable sign of over-careful reading rather than natural speech.
