False friends (or faux amis) are pairs of words in two different languages that seem or sound similar, but differ in meaning.
For instance, actual, which in English is usually a synonym of "real", has a different meaning in other European languages, in which it signifies "current" or "up-to-date" (aktuell in German, actuel in French, actual in Spanish, and attuale in Italian) and has the logical derivative as a verb aktualisieren (German), actualiser (French) meaning "to make current" or "to update". "Actualise" in English ("Actualize" in N.A. English) means "to realize in action, to make real, or to become actual".
