Morphology

in + one + back + pocket

The figurative meaning 'kept secretly or reserved for later use' is directly derivable from the literal image of something placed 'in' a 'back pocket' (a small, often hidden container), so a learner who knows the constituents can infer the idea of keeping something in reserve. This locative/container metaphor is common across languages and follows simple compositional logic, making the expression readily understandable to a B1 learner.

Etymology

The expression in one's back pocket comes from the image of keeping a small tool or card in one's back pocket, where it is hidden but easy to take out when needed. That's why it now means 'kept secretly for later use or advantage'.
