Meaning and Definition
A small paper, foil, or plastic disc used to seal a bottle of milk; also a type of edible fungus (Lactarius) with a milky latex.
Primarily refers to the closure on a glass or plastic milk bottle. In mycology, it denotes a genus of mushrooms (Lactarius) characterized by exuding a milky substance when cut or bruised.
Dialectal Variation
British vs American Usage
Differences
The container sense is more common in British English, recalling traditional milk delivery in glass bottles. In American English, 'bottle cap' or 'cap' is more generic; the specific term 'milk cap' evokes nostalgia or historical context. The mushroom sense is internationally recognized in mycology.
Connotations
UK: nostalgia, traditional daily delivery, environmentalism (reuse). US: historical, less common in everyday use post-1970s. Both: the mushroom sense carries a specialist/foraging connotation.
Frequency
Low frequency in modern general AmE; moderate in BrE among older generations or in contexts discussing traditional practices. Specialist frequency in mycology circles.
