Forms
Januar m (genitive Januars or Januar, plural Januare)[1] Until the 18th century the month was usually called by its Latin name Januarius, inflected with Latin endings (im Januario).[2][3][4] The endingless Januar spread in the second half of the 18th century;[3][2] Lessing uses it from 1753.[3][2]
Etymology
It is a learned borrowing, borrowed from Latin Iānuārius (“of Janus”), short for mēnsis Iānuārius (“the month of Janus”).[5][2][1] The Latin name is usually connected with that of the old Italic god Iānus, god of doors, of going in and out, and so of beginnings,[2][6][7] but Kluge points out that neither the connection nor the reason for the name is certain.[5] Pfeifer and the Duden take the god's name as a personification of iānus (“passage, archway”), compare iānua (“house door”).[2][6] The year began with this month only after the Roman calendar was reformed; earlier it had begun in March.[2][6]
An older borrowing of the same month name is Jänner, Middle High German jenner, Old High German jenner, taken from the variant Vulgar Latin Iēnuārius.[5][2][4] The same learned word is Dutch januari, English January, French janvier and Swedish januari.[5]
Earliest recorded meaning
The older form is recorded first: Old High German jenner is found only in a damaged gloss of the 12th century, translating Latin ianuarius.[4][8] The Latin Ianuarius itself was in German use from the humanist period.[4]
Semantic evolution
Jänner (Middle High German jener, jenner) was long current all over Upper German and was also found in Central and Low German.[4] From the 17th and 18th centuries the newly borrowed Januar, promoted by scholars, pushed it back into the southern dialects; it remains standard in Austria.[4][9][2] Büchner's Lenz still uses Jänner in its first sentence.[9]
Before the Roman names were adopted, Adelung records, the month was called Wintarmanoth “winter month”, a name ascribed to Charlemagne by Rabanus Maurus and Einhard.[10] The god's name has given German janusköpfig “two-faced, ambiguous” and, in the late 20th century, Januswort for a word with opposite senses.[9]
