Forms
août m (plural aoûts)[1] Old French aüst (in two syllables), aost, aoust and oust.[2][3][4] The spelling aoust was current from 1174 to 1759 and août is recorded from 1700.[5]
Etymology
It is inherited from Old French aost, inherited from Vulgar Latin agustus, from Latin augustus (“(the month) of Augustus”), with mēnsis (“month”) understood.[6][2][7][8] The month was renamed in honour of the emperor Augustus, replacing Sextīlis, the sixth month of the old Roman year.[6][2] The form without /au/ is found in Late Latin from the 4th century.[6] The emperor's title, meaning “consecrated, venerable”, comes from augur, connected with augeō (“to increase”).[5] It is a doublet of auguste1.[1]
Because the word had become so short, northern dialects often remade it in two syllables or strengthened it with mois.[7] Cognate with Romanian august, Italian agosto, Spanish agosto, Portuguese agosto, Occitan agost and Catalan agost.[5][7]
Earliest recorded meaning
It is first recorded as aüst in Philippe de Thaon's Comput (1115–1130), naming the month of August.[6]
Semantic evolution
Besides the month, the word meant “harvest time, the harvest” from about 1170;[6][2] this sense lasted into the 17th century and is still used by La Fontaine, but has only a literary value now, though it lives on in dialects.[2][7] It produced the old derivatives aoûter “to harvest” and aoûtage.[2]
La mi-août, “the middle of August”, the feast of the Assumption on 15 August, is recorded from the middle of the 12th century.[6][2] Later derivatives follow the changing associations of the month: aoûtat, a midsummer parasite, is a regional word written down at the end of the 19th century, and aoûtien (about 1965) is a person who takes holidays in August.[2]
The pronunciation shrank from two syllables to one: Palsgrave in the 16th century noted /a.o/, but many already said it in one syllable.[4] The TLFi gives /u/ as the norm and calls /au/ archaic or dialectal, like /ut/; the Grand Robert gives /u/ and the common /ut/.[6][3]
