Forms

chaste[1]

The Anglo-Norman and Picard texts often write caste with an unpalatalised initial, a form counted 37 times in the corpora beside 120 for chaste.[3][4]

Etymology

It is a semi-learned word, borrowed from Latin castus (“pure, chaste”), taken from the Latin of the Church.[1][5][6] The FEW files it under the Latin adjective,[7] and Gamillscheg and Bloch–Wartburg call it a borrowing of the 12th century.[8][9] In Latin the word first meant “conforming to the rules and rites”, and the DHLF explains the later sense “free from fault, pure” by its confusion with a form of careō (“to lack”);[5] the OLD too takes castus to be perhaps a participle of that verb.[10] Its Romance cognates include Italian casto, Old Occitan cast and Spanish casto.[11]

Pope takes the kept /s/ of the word as a sign that it was borrowed or re-formed after the time when Old French lost /s/ before a consonant.[12] The masculine has the ending ⟨-e⟩ of the Latin feminine casta, a form Van Daele and Tobler–Lommatzsch describe as serving for both genders.[13][14]

Earliest recorded meaning

The DEAF's earliest record is the Anglo-Norman Lapidaire apocalyptique, probably by Philippe de Thaon, of the first third of the 12th century, in a manuscript of the late 13th century; it already has both caste and chaste.[15][4] The AND dates its first citation 1113–1119, and Philippe de Thaon's Comput of those years has caste.[2][16] The sense is that of the Latin of the Church: a person who keeps body and soul pure.[7][2]

Semantic evolution

From the first texts the word described a person, above all one living without sexual relations: in Chrétien de Troyes's Cligès a man qui chaste ne se vialt tenir “who will not keep himself chaste” is told to follow Saint Paul's advice.[17] From the late 12th or early 13th century it also qualified things, as in the Moralités sur Job, which speak of the chaste movements of the heart.[6][14] The Middle French examples of the DMF use it for one who abstains from all sexual activity under a vow, and especially for a woman who keeps from unlawful love.[18]

The form caste lasted into the 17th century.[7] The word was little used in classical French: Gamillscheg notes that Racine changed chaste to noble in a line of Phèdre.[8][6] It returned with symbolic and literary uses such as chaste feu in Ronsard, 1552, and was applied to style before 1676; modern French has chaste.[6][5] The abstract noun was first chastee, from about 1121, which the learned chasteté replaced from 1180 on.[5]
