What does despumate mean?
Despumate is a formal English verb meaning to skim off the froth or scum that collects on the surface of a liquid, and by extension to purify that liquid by removing it. It derives ultimately from the Latin noun spuma, meaning foam, via the Late Latin despumare, 'to skim off the scum', entering English in the seventeenth century. The word belongs mainly to technical registers: historical chemistry texts describe despumating solutions during distillation or crystallisation, brewers despumate boiling wort, and cooks may be said to despumate a stock when they ladle away the greyish impurities that rise as it simmers. Though rarely heard today, it survives in dictionaries and in the derived noun despumation, which names both the act of skimming and the froth itself. For writers seeking an exacting alternative to the plain word skim, despumate offers precision with a distinctly learned flavour.

Etymology of despumate
Despumate comes from the Latin verb despumare, formed from de- ('off, away') plus spuma ('foam'), literally 'to skim the foam off'. The term entered English in the seventeenth century, when it was used in alchemical and early chemical writing for the purification of liquids. It shares its root with spume (sea-foam), the adjective spumous, and the Italian sparkling-wine descriptor spumante.
