morso

Forms

morso m (plural morsi)^[1]

Etymology

It is inherited from Latin morsus (“a bite”), the action noun formed on the past participle of mordeō (“to bite”).^[2][3][4][5] Devoto–Oli and Sabatini–Coletti give the neuter morsum, “a piece bitten off”, as the source.^[6][7][5] The same word is French mors, Occitan mors and Catalan mors, and Logudorese has mossu (“mouthful”).^[2][4] DEI treats the sense “bit of a bridle” as a separate entry, but derives it from the same word.^[8]

The Latin verb is an iterative present with the o-grade of a root meaning “to crush, bite”, Proto-Indo-European *h₂mord-(e)ie-, since biting is a repeated action.^[9] Nocentini finds its only sure comparison in a Sanskrit verb meaning “to crush, grind”, and DELI notes that it has few Indo-European connections.^[2][10]

Earliest recorded meaning

GRADIT and Nocentini date the word to before 1276, in the sense of an act of biting.^[3][2] The GDLI's quotations open with Pannuccio del Bagno: Piggiore stimo che morso di capra (“I deem it worse than a goat's bite”).^[11]

Semantic evolution

The bit of a bridle is named in Old Italian, in the translation of Crescenzi and in the Trattato delle Mascalcie, and Petrarch used it.^[12][13] From there come the figurative mettere il morso “to curb someone” and stringere or allentare il morso “to tighten” or “loosen the reins”.^[14][3] Old Italian also used morso for a mouthful, and the diminutive morsello for a small bite.^[13]

Figurative senses for sharp pain and torment are old: Sabatini–Coletti quote Dante's come t'è picciol fallo amaro morso! (“how bitter a sting a small fault is to you!”).^[7] The old plural could be feminine, le morsa, and there is a regional form morzo.^[11] Latin morsus also gave morsicare “to bite” through Late Latin, and the neuter plural morsa gave the Italian word for a vice.^[10][2]

Usage notes

Morso is also the past participle of mordere, used as an adjective.^[3][15][16] A morsi means “with the teeth”, without cutlery or as a weapon, and dar di morso “to bite”, in literary use also “to criticise”.^[6][16] DEI and REW list a separate, obsolete morso “walrus” (16th century, Ramusio), which goes back through Russian to a Finnic or Lappish word, like French morse (1559).^[8][4]
