chiavistello

Forms

chiavistello m (plural chiavistelli)^[1] Old Italian forms include chiavistellu and chiavistiello.^[2] In Tuscany there are also forms with an /r/, such as chiavistrello at Montepulciano in 1753.^[3][4]

Etymology

It is inherited from Latin claustellum (“small lock; keyhole”), reshaped under the influence of chiave (“key”).^{[5][6][7][1][3]} DELI, GRADIT and Zingarelli give the Latin form with an asterisk as a spoken Latin *claustĕllum, while Nocentini notes that Petronius has it as clostellum and reconstructs the crossed form as *clavistellum.^[5][6][8][9] The LEI finds that the Latin word survives only in Italo-Romance, always with the intrusion of clāvis (“key”).^[3]

The Latin word is a diminutive of claustrum (“bar, bolt; lock”) with the suffix -ellum.^[10][1][3] The base noun, the source of chiostro, is formed from claudō (“to close”) with the instrument suffix -trum.^[10][1][5] Wiktionary traces it to Proto-Indo-European *kleh₂ud- (“key, hook, nail”) and relates it to the Latin word for “key”.^[1] Tommaseo had already insisted that the word comes from the verb “to close” and not from the Italian word for “key”.^[11]

Earliest recorded meaning

The first record is a Florentine document of 1288, the register of Santa Maria a Cafaggio.^[2][3][9] The sense was the same as today: a long iron bar that slides in rings or hooks fixed to the leaves of a door or window to lock them.^[2]

Semantic evolution

DELI's first literary record is in Giovanni Villani (before 1348), who tells how the people of Arezzo took the bolt of a Florentine gate and carried it home in contempt.^[5][12] Franco Sacchetti describes a small door “locked with bolt and lock and key” (con chiavistello e toppa serrato a chiave).^[12] Zingarelli records the phrases tirare il chiavistello “to open” and mettere il chiavistello “to lock”, and the old baciare il chiavistello, to resolve never to return to a house or place.^[8]

Oudin's dictionary of the 17th century gives a slang sense “penis”.^[4] In the 20th century writers used the word for a skeleton key.^[3] Modern technical language uses it for devices that lock a mechanism, the sliding breech bolt of a break-action shotgun, and a fixed screw in some clocks.^[6][13]
