cohabitation
C1Formal
Definition
Meaning
The state of living together and having a sexual relationship without being married.
The state of two or more groups, parties, or entities living or existing together, often reluctantly or in an uneasy arrangement (e.g., political cohabitation).
Linguistics
Semantic Notes
Primarily denotes an unmarried romantic partnership, but has a strong secondary political meaning (especially in French/European politics) where opposing parties must share power.
Dialectal Variation
British vs American Usage
Differences
Meaning is largely identical. In political contexts, 'cohabitation' is more common in UK/European discourse describing a president and prime minister from opposing parties. In the US, 'divided government' is a more typical term.
Connotations
In both varieties, the romantic sense can carry neutral, positive, or slightly negative connotations depending on context and speaker. Slightly more formal than 'living together'.
Frequency
Slightly higher frequency in UK English due to the established political usage. The romantic sense is common in legal, sociological, and news contexts in both.

Translation Traps (for Russian speakers)
- Avoid direct translation from Russian 'сожительство' as it is often more negatively connoted, implying promiscuity or informality. 'Cohabitation' is a more formal, neutral term.
Common Mistakes
- Misspelling as 'co-habitation' (hyphen is non-standard).
- Confusing with 'coexistence', which lacks the romantic/domestic implication.
- Using the verb 'cohabit' incorrectly (e.g., 'They cohabit together' is redundant).
