Etymology

Etymology tree Proto-Indo-European *lewbʰ-der. Proto-Germanic *laubō Proto-West Germanic *laubu Old English lēafa Middle English bileve English belief From Middle English bileve, from Old English lēafa, from Proto-West Germanic laubu from Proto-Germanic laubō. Compare German Glaube (“faith, belief”). The replacement of final /v/ with /f/ is due to the analogy of noun-verb pairs with /f/ in the noun but /v/ in the verb, creating a pair belief : believe on the model of e.g. grief : grieve or proof : prove.
