Forms

mezzo (feminine mezza, masculine plural mezzi, feminine plural mezze); noun mezzo m (plural mezzi); also an adverb[1][2] The oldest forms are mezo (1158) and the Veronese meço.[3]

Etymology

It is inherited from Latin medius (“middle”), the adjective, and its neuter medium (“the middle, the space between”), used as a noun.[3][4][2] The word came down through popular speech, while medio is the learned doublet of the same Latin word.[3][1] The same word is Old French mi, Occitan mieg, Catalan mig, Spanish medio, Portuguese meio and Romanian miez, which means “kernel, pith” in Romanian.[4][5]

The Latin adjective goes back to Proto-Italic *meðios, from Proto-Indo-European *médʰyos (“middle”); it is related to Sanskrit मध्य (mádhya), Ancient Greek μέσος (mésos), Gothic 𐌼𐌹𐌳𐌾𐌹𐍃 (midjis) and English mid.[6][4][1]

Earliest recorded meaning

DELI's first record is mezo in the Tuscan Testimonianze di Travale of 1158, in a sentry's rhyme quoted there: “Guaita, guaita male: non mangiai ma mezo pane” (watch, watch badly: I ate but half a loaf).[3][7] The form mezzo is in the Novellino at the end of the 13th century.[3]

Semantic evolution

The noun “half” is in Bono Giamboni before 1292, and Dante uses the word for the middle, the centre, and for “intermediate”.[3] The sense “means, way of reaching an end” is in Ugo Panziera before 1330;[3] Galileo, before 1642, used mezzo for the medium in which a physical event takes place.[3] Before 1829 Melchiorre Gioia used mezzi di comunicazione for vehicles, and by 1950 mezzo alone could mean any means of transport.[3] Purists judged a mezzo di a calque of French au moyen de beside older per mezzo di, and mezzi “money” a Gallicism too.[3]

Many compounds were made with it: mezzadro “sharecropper” (1516–1520), mezzanotte, mezzogiorno, mezzaluna and the football term mezzala (1921).[3] In music mezzo, between forte and piano, was taken into German by 1732, and English used it in compounds such as mezzotype (1894).[8]

Usage notes

A second mezzo, pronounced with a close /e/ and voiceless /tts/, means “overripe” of fruit and, figuratively, “corrupt”; it is Tuscan, Umbrian and Roman, recorded about 1340.[2][10][1] It continues a rustic Vulgar Latin *mētius, a variant of Latin mītius (“softer”), the comparative of mītis (“mild, ripe”), and DELI numbers it as the first homograph.[3][4] Phrases with mezzo “half, middle” include andarci di mezzo “to suffer the consequences”, togliere di mezzo “to get rid of”, and per mezzo di “by means of”.[2][3]
