Morphology

in + at + the + deep + end

The phrase contains the literal chunk 'deep end' (the deep part of a pool) which readily suggests a metaphor of being placed somewhere difficult or risky; a learner who knows 'deep' and 'end' can often infer this image. However, the idiomatic use of the whole prepositional phrase ('in at the deep end' / 'thrown in at the deep end') requires a metaphorical mapping and specific collocation knowledge, so the meaning is not fully predictable without exposure.

Etymology

In at the deep end comes from the image of someone put into the deep end of a swimming pool where the water is deep and they must swim straight away. So it means 'placed in a difficult situation without preparation'.
