What does locker mean?
A locker is a storage cabinet or compartment that can be secured with a lock. Its typical uses include keeping books, clothing, valuables, tools, or other personal belongings in schools, workplaces, gyms, stations, and similar places. The word often implies a numbered or assigned storage unit, particularly when someone speaks of having a locker or being given a locker key. A locker is generally smaller than a cupboard or wardrobe, and the lock is an important part of the concept: a locker protects its contents from access by others. In British English, the term is especially common for school and changing-room storage, while American speakers use it in many similar settings. In a broader commercial context, a locker can also mean a secure compartment for storing goods, documents, or equipment.

Where does locker come from?
The word is formed in the 16th century from “lock” and the suffix “-er,” originally referring to a person who locks or secures something. Its use for a secure storage cabinet developed later, by analogy with other pieces of furniture and storage receptacles. The older sense of a lockkeeper or someone entrusted with locking up continues in some institutional contexts.
