inmate
B2Formal, Official, Technical (legal/penal contexts)
Definition
Meaning
A person who is confined to an institution such as a prison, hospital, or psychiatric facility.
While historically referring to anyone living in a shared residence (e.g., a lodger), the modern primary meaning is specifically someone detained in a penal or custodial institution. It can also refer to residents of other closed institutions like care homes or sanatoriums.
Linguistics
Semantic Notes
The term focuses on the state of confinement within an institution. It is often used in administrative, legal, and journalistic contexts. It is a status label and can be seen as dehumanizing if used without context, as it reduces the person to their institutional status.

Differences

Connotations
Equally formal and institutional in both varieties. In both, it is the standard term used by correctional services and the legal system.
Frequency
Slightly higher frequency in American English due to larger prison population and media coverage, but the word itself is equally common in relevant contexts in the UK.

Translation Traps (for Russian speakers)
- Avoid confusing with "сокамерник" (cellmate/sharing a cell). "Inmate" is broader. "Заключённый" is the closest equivalent.
- Do not use for someone simply living in a flat/hostel - the old meaning is obsolete.
Common Mistakes
- Using it for students in a boarding school (archaic).
- Spelling as 'innmate' (double n).
