chiave

Forms

chiave f (plural chiavi)^[1] Old forms include Old Italian clave, Old Italian chiavi, Old Italian ciave and Old Italian chlave.^[2] Northern dialects had Lombard chiaf and Ligurian clhave.^[3]

Etymology

It is inherited from Latin clāvis (“key; bar, bolt”), from the accusative.^[4][5][6][1] The word is pan-Romance: Romanian cheie, Dalmatian kluf, Friulian clâf, Romansh clav, French clef, Occitan clau, Catalan clau, Spanish llave, Portuguese chave and Sardinian giae.^[5][7][8] DÉRom reconstructs a Proto-Romance form for it.^[9]

The Latin noun shares its root with claudō (“to close”) and clāvus (“nail”), the sources of chiudere and chiodo.^[5][4] De Vaan traces it to Proto-Italic *klāwis (“bar, bolt”) and Proto-Indo-European *kleh₂u- (“to close”), with cognates in Ancient Greek κλείς (kleís, “bar, bolt; key”) and Russian ключ (ključ, “key”).^[10][5] DEI and Devoto think that the Latin word may have been a technical loan from Doric Greek.^[11][12]

Earliest recorded meaning

The TLIO's first record is the Venetian Proverbia que dicuntur of the late 12th century, in the form clave.^[2][3] The first Tuscan record is a letter of Andrea de' Tolomei of 1262, with the sense “metal tool for opening and closing locks”.^[4]

Semantic evolution

The figurative sense “the element that explains or solves something” is already found in Guidotto da Bologna at the beginning of the 13th century.^[4] Dante's angel at the gate of Purgatory has a gold key and a silver one, and the keys became the emblem of St Peter and of the Church's authority.^[13][14] The cipher key is recorded in Giordano Bruno (1584–1585).^[4]

In music the word names the clef from the 15th century (Pulci, before 1484); Zarlino explained that just as a key opens a door and shows what is inside, the clef opens the melody and shows its intervals.^[4][15] French borrowed this sense as chiave in 1703 and German in 1732.^[15] The phrase in chiave di, first of the violin or bass clef, came to mean “in the manner of”, for example in chiave ironica; it is recorded from 1925.^[4] Since 1952 chiave has also been used after a noun as an invariable adjective, “key, decisive”.^[4] Technical senses include the spanner (chiave inglese) and the keystone of an arch (chiave di volta, 1875).^[5][13]
