Etymology: "Spuma" is the Latin word for foam, and it has come into English mainly as a technical term rather than an everyday one. Latin "spuma" was related to "spuere", to spit, a connection that captures how foam forms: air and liquid churned together until they spit out bubbles. The word is an ancestor of the modern Romance words for foam, such as Italian "spuma" and French "écume"-type forms in related languages, though French itself uses a different base. In English, "spuma" survives in scientific and literary contexts, where it names a light, frothy mass, such as the foamy sea spray or the bubbly froth that forms on cells and fluids. English borrowed the Latin form directly rather than through French, which is why it looks so unchanged from its source. Its use in English is largely confined to writers and specialists, so most readers meet it first in Latin texts or in nature descriptions.
