Forms

chave f (plural chaves)[1] Old Galician-Portuguese wrote chaue and chave; a 14th-century text has the Latinising claue.[2]

Etymology

It is inherited from Latin clāvis (“key, bar”), written Old Galician-Portuguese chaue in the oldest Portuguese record, of 1277.[2][3][1] The Latin group /kl/ at the start of the word changed to ⟨ch⟩, as Vieira already explained in 1871.[4] The standard pronunciation is /ʃ/, while northern Portugal has /tʃ/.[1] Houaiss calls the word the popular divergent of the learned clave, which comes from the same Latin word.[2][1]

The same Latin word is Galician chave, Spanish llave, Catalan clau, French clé, Italian chiave and Romanian cheie.[5][1] García de Diego records the Portuguese and Galician form beside the Aragonese and Catalan form clau.[6] The Spanish word is recorded from the earliest Castilian texts, and Berceo still wrote Old Spanish clave.[7][8]

The Latin word goes back to *klāwis (“bar, bolt”), from *kleh₂w- (“to close”), and is related to κλείς (kleís, “bar, bolt; key”).[9][1] Wiktionary glosses the root as a hook or pin of the kind once used to fasten doors, and notes that the word may have reached Latin through Greek.[1]

Earliest recorded meaning

The first record is of 1277, spelt chaue.[2] In the Cantigas de Santa Maria the word is used both literally, for keys worn at the belt (chaves, que tragia na cinta), and figuratively: Eve shut the heavens sen chave “without a key”, and the Virgin is chav' é de nossa fe “the key of our faith”.[10]

Semantic evolution

The figurative sense of a means of access or of authority goes back to the medieval language.[10] Barbosa's dictionary of 1611 already lists chave feytiça, a false key.[11] Bluteau describes the parts of a key, and Folqman (1755) lists chave mestra, the key that opens many locks.[12][13][14] Morais (1789) adds the figurative chave mestra of the sciences and the sense of a stronghold that commands a pass or a stretch of sea.[14] In land surveys a chave was a corner or point the ground makes to one side, recorded in a document of 1482.[15]

Later dictionaries extend the word to any tool for tightening or loosening screws and nuts, to the device for winding a clock, to the keys of wind instruments and to the curly bracket.[16][17][2] Modern senses include a password or cryptographic key, a group in a tournament and, used after another noun, “essential, decisive” (palavra-chave).[1][18]
