primo

The word 'primo' entered English directly from Italian and Spanish, where it functions as an adjective meaning 'first'. Its ultimate source is the Latin 'primus', meaning 'first, foremost, chief, principal', which itself derives from the Proto-Indo-European root 'per-' meaning 'forward, through, in front'. In musical terminology, 'primo' was adopted to designate the first or leading performer, especially in a piano duet. This concrete musical sense later facilitated a figurative extension in informal English, where it came to describe anything of the first or highest quality, completing its journey from a simple ordinal number to a term of high praise.
