guscio

Forms

guscio m (plural gusci)^[1] Old Italian forms include ghuscio, guscia and gussa.^[2] The feminine guscia is used in the northern dialects and reaches Pisa, Lucca and Prato.^[3][1]

Etymology

Its origin is disputed.^[4][5] In DELI's view it is borrowed from Ancient Greek κύστιον (kústion, “small bladder”), the diminutive of κύστις (kústis, “bladder”): it calls this the only explanation plausible enough so far, proposed by Ribezzo and argued by Alessio, with strong support in Friulian scusse.^[4] DEI and GRADIT give the same source.^[3][6]

Nocentini, followed by the TLIO, derives it instead from Vulgar Latin *custium, from *costeum, a derivative of Latin costa (“rib”) in the sense “vein of a leaf”, then “outer leaf of a vegetable” and “peel”.^[5][2] For him the stressed vowel was raised before /-iu-/, as in biscia and uscio, and the initial /k/ was voiced before a back vowel.^[5] He rejects the Greek source because the word is rare, recorded only as a plant name, and because the late Greek /y/ does not explain Italian /u/.^[5] The southern cosca, from Late Latin costula, is a parallel: French cosse “pod” has the same origin, and in Italy the type of the present word covers the centre and north, the other the south.^[5]

DELI also mentions a reconstructed *custium (“custody”) of the family of Latin custos (“guardian”), which Devoto prefers, Skok's *cusceum, and Hubschmid's root of a pre-Latin substrate.^[4][7] Nocentini finds Hubschmid's comparison too wide for so general a word.^[5] Prati and the GDLI consider the Greek source improbable, and the GDLI calls the word of uncertain origin.^[8][9] It has been compared with French gousse (“pod”), recorded only from 1520;^[3][9][5] DEI holds that the Friulian form and the Italian dates rule out a loan from French.^[3][9][5] Older proposals from Germanic, such as Old High German hulsa (“husk”), have been abandoned.^[10][11]

Earliest recorded meaning

The TLIO's first record is in the Florentine translation of the Tesoro of the late 13th century.^[2] DELI dates the word to Giordano da Pisa, before 1311, for the hard outer covering of certain fruits and of the eggs of birds and reptiles.^[4] Giordano asks whether the whole sea could fit in a little nutshell: Potrebbe capere tutto ’l mare in un piccolo guscio di noce?^[9]

Semantic evolution

In Old Italian the word covered the woody shell of almonds, walnuts and chestnuts, the husk of cereals and legumes, eggshells, the shells of crustaceans and molluscs and the silkworm's cocoon; it also meant a trifle and, in rhetoric, the allegorical veil over a deeper truth.^[2] Boccaccio has a man who cracked nuts and sold the shells.^[9] Luigi Pulci uses it for the shell of molluscs before 1484, and Vasari in 1550 for a structure whose covering bears the load.^[4][8]

Later uses include the hull of a ship, a mattress tick and a small boat, and guscione “a chestnut that has not grown well” (1869).^[8] Modern figurative senses are the small, unsafe boat and the closed world one withdraws into, as in uscire dal guscio “to come out of one's shell”.^[6][12]
