What does closet mean?
A closet is a small, usually enclosed space built into a building, most commonly used for storing clothes, linens, or other household items. In American English it is the everyday word for such a storage compartment — whether a shallow hall closet, a linen closet, or a spacious walk-in closet — while British speakers more often say cupboard or wardrobe. Historically, the word also denoted a small private chamber, such as a study or a room for prayer and contemplation, and this sense lingers in phrases like 'a closet intellectual'. Figuratively, 'the closet' has come to represent concealment itself: someone who keeps a significant part of their identity secret may be described as being 'in the closet', while revealing it is 'coming out'. Fixed idioms like 'a skeleton in the closet' use the same idea of things hidden away behind a closed door. Derived forms include the adjective and verb 'closeted', meaning confined or kept in private.
A small enclosed room or built-in cupboard used for storage, or (chiefly in historical or British usage) a small private room such as a study or chapel.
"She packed the spare blankets into the hallway closet."
The storage sense is standard in American English; British speakers typically prefer 'cupboard' or 'wardrobe'. The private-room sense is now largely historical or literary.
(usually passive, 'closeted') To confine someone in a private room, especially for discussion or negotiation away from public view.
"The negotiators were closeted with the president for hours."
Almost always used in the passive construction 'be closeted with someone'.
(attributive, often hyphenated) Denoting something done privately or secretly, or someone who hides a part of their identity — e.g. 'a closet liberal', 'a closet case'.
"He was a closet jazz fan who never mentioned music at the office."
Common in the fixed expressions 'closet case' and, historically, 'closet queen'; the attributive use signals secrecy or concealment.
Regular plural, formed simply by adding -s.
"Every bedroom in the house has a walk-in closets—"
The phrase 'come out of the closet' was popularized in the late 1960s by gay rights activists, turning a humble piece of furniture into one of the most powerful metaphors in modern English.

Etymology of closet
The word 'closet' comes from Old French 'closet', a diminutive of 'clos', meaning an enclosed space, which derives ultimately from the Latin verb 'claudere', meaning 'to shut or close'. It entered English in the Middle Ages, initially referring to a small private room rather than a mere storage cupboard. Because of its shared Latin root, it is related to a whole family of words about enclosure and shutting, including 'close', 'closure', 'cloister', and 'recluse'. Over time the architectural sense of a private chamber gave way in American usage to the storage-cupboard sense that dominates today.
