Origin: 1530–40; < Latinaffābilis that can be spoken to, courteous, equivalent to af-af- + fā- speak (see fate) + -bilis-ble, perhaps via Middle French
late 15c., from O.Fr., from L. affabilis "kind, friendly," lit. "he who can be (easily) spoken to," from affari "to speak to," from ad- "to" + fari "to speak" (see fame).
