Morphology

lose + one + wits

The phrase is directly built from 'lose' (to cease to have) + 'one's wits' (one's capacity for clear thought), so a learner who knows those words can infer that it means to lose the ability to think clearly. The possessive 'one's' is grammatical framing only and the compositional pattern is cross-linguistically common, making the MWE immediately understandable to B1 learners.

Etymology

Lose one's wits may come from the idea that wits are like small inner lights or quick thoughts, and to lose them is like the lights going out. That's why it means 'to become very confused or unable to think clearly'.
