Synonym discussion

Sense: noun/1

Foam is the broadest of these terms and can describe any mass of tiny bubbles in a liquid — from sea foam on a beach to the foam on a latte. Lather, by contrast, is specifically linked to soap or detergent and is the natural word for shaving cream foam or hand-washing bubbles. Froth suggests a lighter, airier consistency and is most common for the foam on beer or cappuccino; it carries a more delicate, almost playful feel than lather. Suds is an informal, everyday word limited to soapy water, especially from dishwashing or laundry — nobody says 'shaving suds.' Bubbles is the most general term for individual spherical pockets of air, and 'soap bubbles' overlaps with lather but has a childlike, recreational association. In everyday use: 'He worked up a good lather while shaving,' but 'The kids blew soap bubbles in the garden.'

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

Lather comes from Old English 'lēaþor,' which meant washing soda or the froth from soapy water. It is related to Old Norse 'lauðr' (washing foam) and goes back to a Proto-Germanic root. The word first referred to soap bubbles, then was extended to the foamy sweat on a horse (by the 1500s), and later took on the metaphorical sense of emotional agitation — the image of someone worked up into a state as foamy as a lathered horse.
