cleavage
B2The word spans formal, technical, and informal registers depending on context. The 'breasts' sense is informal and carries potential for being considered objectifying or vulgar.
Definition
Meaning
A division or split between two things, often resulting from pressure or a fundamental difference.
1) The space between a woman's breasts, especially when made visible by clothing. 2) In geology, the splitting of rocks or crystals along natural planes of weakness. 3) In biology, the process of cell division in early embryonic development.
Linguistics
Semantic Notes
The dominant contemporary, non-specialist meaning refers to the visible area between breasts, heavily influenced by fashion and media. The original and technical meanings (division, geology, embryology) remain primary in their respective fields but are less frequent in general discourse.
Dialectal Variation
British vs American Usage
Differences
No significant difference in core meaning. Both varieties use all senses. The informal 'breasts' sense may be slightly more prevalent in British media/tabloids, while the technical senses are equally common in academic contexts in both regions.
Connotations
In everyday conversation, the word immediately and strongly connotes the 'breasts' sense for most speakers, which can make its use in technical contexts (e.g., 'rock cleavage') momentarily jarring or humorous.
Frequency
The anatomical sense is high-frequency in informal/popular contexts. The geological and biological senses are low-frequency outside specialist fields. The 'division' sense (e.g., 'social cleavage') is mid-frequency in formal/academic writing.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- False friend with 'кливаж' (clivage – a rare geological loanword).
- Direct translation 'расщепление' works for geology/biology but not the informal sense.
- For the 'breasts' sense, a direct translation sounds overly technical/crude; 'декольте' (décolleté) or periphrases are often preferred.
Common Mistakes
- Using it in a formal mixed-gender setting intending the 'division' sense, unaware of the strong informal connotation.
- Misspelling as 'clevage'.
- Overusing the word in writing when 'division', 'split', or 'rift' would be clearer and less loaded.

FAQ
Frequently Asked Questions
It is not a swear word, but its primary informal meaning relates to a sexualized part of the body. Using it in general conversation, especially to describe a person, can be considered objectifying, inappropriate, or overly blunt. It is safest used in its technical contexts.
'Décolleté' (from French) refers to a low neckline of a garment or the area of a woman's body exposed by such a neckline. 'Cleavage' specifically refers to the visible indentation or space between the breasts. 'Décolleté' is often considered a more refined or fashion-oriented term.
No, 'cleavage' is solely a noun. The related verb is 'to cleave', which means to split or adhere strongly to (it has two almost opposite meanings).
Use it precisely and consistently as a technical term ('basal cleavage', 'prismatic cleavage'). Establish the scientific context early in your writing. The technical meaning will override the informal one for your informed reader.
