verb/ɑ̃.bu.ʃe/
to place one's lips against the mouthpiece of a wind instrument; to place the bit in a horse's mouth; to tell off, to antagonize; to argue
Inherited from Middle French emboucher, from Old French embouchier. By surface analysis, en- + bouche + -er. Possibly corresponds to a Vulgar Latin *imbuccāre, from Latin bucca (compare Portuguese and Spanish embocar, Italian imboccare, Romanian îmbuca).
