clarinet (plural clarinets)
clarinet m (plural clarinets)
clarinet n (plural clarinete)
Learned borrowing from Italian clarinetto diminutive of clarino (“trumpet”) (as the first clarinets had a strident tone similar to that of a trumpet)
Alternatively, the word may come from French clarinette, diminutive form of clarine (“bell”), from clarin, from clair (“clear”).
