Cabilero (n.) & Cavaliero (adj.)
Calibero (n.) means gallant or fine fellow. It was sited in Shakespeare’s Henry IV Part 2 (2H4 V.iii.58 [Shallow to all] I’ll drink to Master Bardolph, and to all the cabileros about London [Q; F Cauileroes])
Cavaliero means gallant, valiant or honourable. It was sited in Shakespeare’s The Merry Wives of Windsor three different times (1) MW II.i.181 [The Host says to Shallow] Cavaliero justice, I say!, (2) MW II.i.1196 [The Host says Ford, of Falstaff] Hast thou no suit against my knight, my guest cavaliero?, (3) MW II.iii.67 [The Host aside says to all except Caius] Master guest, and Master Page, and eke Cavaliero Slender.)
In the cruel speech of rejection, Henry V is at some trouble to ensure that Falstaff be given no opportunity of dialogue” (Bloom 277).
