Surface Forms

Morphology

out + of + one + depth

The phrase combines 'out of' with 'one's depth' where 'depth' can be interpreted as a degree of knowledge or competence, so the overall sense 'beyond someone's ability' is compositionally related to the parts. However this is a figurative/metaphorical use of 'depth' and the exact idiomatic collocation may not be fully predictable to a B1 learner without prior exposure, so it is only partially transparent.

Etymology

Out of one's depth comes from the image of being out beyond the depth you can stand in: when the water is too deep you cannot touch the bottom and you have trouble. So it means 'unable to deal' with a situation because it is 'too difficult' or unfamiliar.
