Definition and pronunciation
sleep with — an informal euphemism meaning to have sex with someone; in literal use, it can mean to share a bed or sleep in the same place.
Pronounced /sliːp wɪð/ or /sliːp wɪθ/.
Easy explanation
Sleep with usually means have sex in a polite, non-graphic way. Sometimes it just means two people literally slept in the same bed/room without sex. Context decides which meaning is intended.
Part of speech and grammar
- Verb phrase: sleep with; slept with; sleeping with.
- Pattern: sleep with + person (She slept with her partner).
- Mutual form: They slept with each other.
- Time/aspect: started sleeping with…; have slept with….
- Literal uses: sleep with + thing/condition (sleep with the TV on; sleep with the window open).
Register and tone
Neutral-to-gentle euphemism for sex; acceptable in everyday conversation, journalism, counseling, and education. Softer than slang (bang, screw), less clinical than have intercourse.
Connection to sexuality
Yes, commonly. Sleep with typically means to have sex between consenting adults. When discussing consent, safety, or health, switch to clear terms (have sex; protected/unprotected sex; sexual intercourse).
Common collocations
- sleep with [someone]
- have/started/stopped sleeping with [someone]
- slept with each other / with multiple partners

Idioms and set phrases

Prepositions and nuance
- with + person — usual sexual sense: He slept with his ex.
- with + object/condition — literal: I slept with the fan on.
- together (variant phrase) — sleep together ≈ sleep with (slightly more mutual-sounding).
- Contrast: sleep over (stay the night), sleep on it (delay a decision); neither implies sex.
