spumare

Spumare is an Italian verb meaning to form or produce foam or froth; to foam. It describes the action of liquids that become bubbly, such as during boiling, shaking, or fermentation, and can also refer to foam around the mouth in medical or veterinary contexts. The related noun spuma denotes foam or froth, and the adjective spumoso means foamy or frothy. The word derives from the Latin spuma, foam.

In everyday language, spumare is used to describe foaming phenomena in liquids, for example when heating milk, beer, or wine, or during mixing and agitation in culinary or industrial processes. It can also be used metaphorically to indicate a rapid buildup or agitational froth on a surface. In medical or veterinary contexts, the expression spumare dalla bocca is used to describe foam forming at the mouth, a symptom associated with certain diseases or severe intoxication.

Cognate and related terms include schiumare (a more common synonym for foaming), spuma (foam), and spumoso (foamy). The concept also appears in coastal or maritime imagery, where waves or sea spray may be described as spumanti or spumose when foaming at their crests.

Overall, spumare covers both the everyday physical phenomenon of foam formation in liquids and specific figurative or clinical usages, while sharing its root with other Romance-language terms for foam.
