Definition
Meaning
Relating to or characterised by a mental condition involving persistent, unwanted thoughts (obsessions) and repetitive behaviours or mental acts (compulsions).

Linguistics
Semantic Notes
Primarily used as an adjective (obsessive-compulsive disorder) or as a noun (an obsessive-compulsive) in clinical contexts. In extended, non-clinical use, it often describes meticulous or perfectionist tendencies. Lay usage can trivialise the clinical condition.

Connotations
Identical core clinical meaning. In informal extended use, both varieties use it similarly to describe fussiness or extreme tidiness.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'навязчиво-компульсивный' in non-clinical, casual conversation as it sounds overly clinical. In informal extended use, Russian might use 'помешанный на порядке/чистоте' or 'педантичный'.
- The noun 'an obsessive-compulsive' does not have a direct one-word equivalent; use 'человек с ОКР' or 'страдающий ОКР'.
Common Mistakes
- Using 'obsessive-compulsive' as a noun without an article ('He is obsessive-compulsive' is fine as adjective; 'He is an obsessive-compulsive' is the noun form).
- Misspelling as 'obsessive compulsive' without the hyphen when used as a compound adjective before a noun (e.g., 'obsessive-compulsive disorder' is correct).
- Trivialising the clinical condition by using it to mean simply 'neat'.

FAQ
Frequently Asked Questions
'OCD' is the abbreviation for Obsessive-Compulsive Disorder, the clinical condition. 'Obsessive-compulsive' is the adjective form describing things related to that disorder or, in loose informal use, similar behaviours.
In casual conversation, it happens, but it is often considered inaccurate and potentially offensive, as it trivialises a serious mental health condition. Terms like 'meticulous', 'tidy', or 'perfectionist' are more appropriate.
When used as a compound modifier before a noun (e.g., disorder, behaviour), it requires a hyphen: 'obsessive-compulsive disorder'. When used predicatively (after a verb like 'is'), the hyphen is sometimes omitted in informal writing, but retaining it is clearer.
In the clinical term, they are linked but distinct: obsessions are the persistent thoughts, and compulsions are the repetitive actions performed to alleviate the anxiety from those thoughts. Outside the clinical term, the words can be used separately.
