Morphology

PO + box

The meaning 'a numbered compartment at a post office' is directly compositional from 'PO' (post office) + 'box' (container); a learner who knows both constituents can infer it refers to a mailbox at the post office. Although 'PO' is an abbreviation and the phrase is a conventional collocation, the semantic relation is straightforward and cross-linguistically parallel (e.g. 'post office box'), so it is accessible to B1 learners.

Etymology

PO Box comes from the parts PO, short for 'post office', and box. Imagine a row of small numbered boxes at the post office where people pick up their 'mail'. That's why PO Box means 'a numbered compartment' you use to receive mail instead of your home 'address'.
