Pronunciation

Forms

doux (feminine douce, masculine plural doux, feminine plural douces)[1] Old French dulz, douz (12th century); doux from the 16th century.[2][3] The feminine douce (dulce in the Chanson de Roland) was created in French, Latin dulcis had one form for both genders.[4][2]

Etymology

It is inherited from Old French dulz, inherited from Latin dulcis (“sweet; pleasant, charming; dear”).[5][3][4][6][7] Rey and the Petit Robert connect the Latin word with Ancient Greek γλυκύς (glukús, “sweet”), from an earlier “*dlukus”.[3][8] Bloch and Wartburg note that the other Latin adjectives for softness fared differently: “lēnis” survives only in Romanian lin, and for “suāvis” compare suave.[4]

Cognate with Romanian dulce, Italian dolce, Catalan dolç, Spanish dulce and Portuguese doce.[8]

Earliest recorded meaning

The Chanson de Roland (about 1100) has France dulce “sweet France”, dulz païs and ewes dulces, fresh water.[5][9]

Semantic evolution

From the first texts the adjective has its full range of uses: of taste, touch (liz dulz, about 1150), the weather (vanz dolz, Chrétien de Troyes, about 1176) and people (douce fille, about 1170), and in courtly lyric ma douce amie.[5][3][9] Later additions are the technical “ductile” of metals (1690) and prix doux “moderate prices” (1808).[3][10]

The adverb (1531) gave filer doux “to toe the line” (1583) and classical tout doux! “gently!”.[3][5] Familiar en douce “on the quiet” dates from 1884.[5][3] As a noun le doux is a neuter (1669), and in 19th-century slang a liqueur, opposed to le dur (1805).[3][10]
