out of one's depth
Meaning: Beyond one's capability.
Example: “In that advanced physics class, I was out of my depth.”
Origin: Nautical and literal at its root: a swimmer or wader who moves into water deeper than their own height can no longer touch bottom, losing the solid footing that makes staying safely afloat manageable. The phrase in this literal sense dates to around 1600, and Shakespeare's Henry VIII already has the closely related "beyond my depth," suggesting the image was already familiar by his time. The figurative sense — lacking the skill, knowledge, or experience to cope with a situation — developed by the early 1700s, transferring the same loss of solid footing from literal water to any circumstance where a person has moved past what they can reliably handle.
