fresco

The Italian word fresco means “fresh” and comes from a Germanic word akin to the source of English fresh. In the Renaissance, pittura a fresco, meaning “painting freshly,” referred to paint applied while the plaster on the wall was still wet, as opposed to pittura a secco “painting dryly,” in which paint is applied when the plaster was dry. In English, fresco appears earliest as part of the phrase in fresco; it does not appear as a noun referring to a painting until 1670. A different sense of Italian fresco, meaning “fresh air,” appears in the phrase al fresco “outdoors,” borrowed into English as alfresco and used particularly in reference to dining outdoors.
