warble: [14] The etymological notion underlying the word warble is of ‘whirling around’; its application to sounds, originally in the sense ‘whirl of notes, trill’, is a secondary development. It was borrowed from Old Northern French werbler, a derivative of the noun werble ‘trill, melody’. And this in turn came from Frankish *hwirbilōn ‘whirl, trill’, which is distantly related to English whirl. (Warble ‘swelling on an animal’s back caused by insect larva’ [16] is a completely different word. It may have been borrowed from the now obsolete Swedish compound varbulde, literally ‘pustumour’, or a related Scandinavian word.)
warble (v.)
late 14c., from Old North French werbler "to sing with trills and quavers" (Old French guerbloiier), from Frankish *werbilon (cognate with Old High German wirbil "whirlwind," German Wirbel "whirl, whirlpool, tuning peg, vertebra," Middle Dutch wervelen "to turn, whirl"); see whirl (v.). Related: Warbled; warbling. The noun is recorded from late 14c.
