Forms

janvier m (plural janviers)[1] Old French jenvier (1119) and janvier (end of the 12th century); Old Picard genvier.[2][3] Anglo-Norman also had genver and janever.[4]

Etymology

It is inherited from Old French jenvier, inherited from Vulgar Latin jenuarius, a popular form found in inscriptions, for classical Latin Iānuārius (“January”);[3][2][5][6] Bloch and Wartburg explain that pretonic ⟨ja-⟩ regularly became ⟨je-⟩ in Late Latin.[3] The Latin word is an adjective “of Janus” used as a noun, short for a phrase with mēnsis (“month”); Iānus was the god of doors, passages and beginnings, who presided over the start of the year.[7][2] Rey connects his name with the common noun meaning “passage, arcade”, perhaps from a root meaning “to go”.[7]

Cognate with Italian gennaio, Spanish enero, Catalan gener, Portuguese janeiro and Old Occitan januer.[2][3][8]

Earliest recorded meaning

It is first found as jenvier in Philippe de Thaon's Comput (1119), meaning “January”.[2][7]

Semantic evolution

The word has kept its single meaning, the first month of the year.[2][5] Set expressions include le premier janvier, New Year's Day, and the familiar du premier janvier à la Saint-Sylvestre “all year round”.[9][5] Le bonhomme Janvier, the month personified, is recorded by Larousse in 1902.[9]

Usage notes
