A lingua franca (/ˌlɪŋɡwə ˈfræŋkə/; lit. ‘Frankish tongue’; for plurals see § Usage notes), also known as a bridge language, common language, trade language, auxiliary language, vehicular language, or link language, is a language systematically used to make communication possible between groups of people who do not share a native language or dialect, particularly when it is a third language that is distinct from both of the speakers’ native languages.
Actually Wikipedia specifically has a note at the top:
In Lingua Franca (the specific language), lingua is from the Italian for ‘a language’. Franca is related to Greek Φρᾰ́γκοι (Phránkoi) and Arabic إِفْرَنْجِي (ʾifranjiyy) as well as the equivalent Italian—in all three cases, the literal sense is ‘Frankish’, leading to the direct translation: ‘language of the Franks’. During the late Byzantine Empire, Franks was a term that applied to all Western Europeans.
So if anything, it’s (roughly) Italian, Greek, and Arabic for “language of the Western Europeans”.
