What does claustrophobic mean?
Claustrophobic describes two related things: a person who experiences claustrophobia — an intense, often irrational fear of confined spaces — and a place or situation so small, enclosed, or crowded that it provokes feelings of anxiety or oppression. An elevator, a crowded train carriage, or a windowless corridor may all be described as claustrophobic, even for those without the clinical condition. The word derives from the Latin claustrum, meaning an enclosed space, combined with the Greek phobos, meaning fear. In everyday use, saying someone is claustrophobic can indicate anything from a diagnosed phobia to a mild discomfort in tight spaces, while calling a room claustrophobic is purely descriptive of its oppressive atmosphere. The word's antonymic counterpart is agoraphobia, the fear of open or public spaces. Its vivid connotations of confinement and suffocation make it a powerful term in both clinical and figurative contexts.
adjectiveSuffering from or relating to an extreme fear of confined spaces. Also used to describe a place that is so small, enclosed, or crowded as to induce such fear or discomfort.

Its root 'claustrum' is Latin for 'shut-in place' — the same word that gave medieval monks the cloister and modern English the word 'conclave.'

Etymology of claustrophobic
Claustrophobic is derived from claustrophobia, a term formed from the Latin claustrum ('enclosed place', the source of 'cloister') and the Greek phobos ('fear'). The compound was coined in the 19th century, when several '-phobia' terms were being formalized in European medical literature. It shares its Latin root with words like 'cloister' and 'close', all pointing back to the idea of shutting in.

How claustrophobic is actually used
The word applies both to people (describing a condition or disposition) and to places (describing their effect). When describing spaces, it carries no implication of clinical phobia; describing people as claustrophobic may refer either to the clinical condition or to a milder dislike of confined spaces.
Easily confused with claustrophobic
A claustrophobic person fears enclosed spaces, whereas an agoraphobic person fears open or public spaces from which escape might be difficult.
