Forms
ontem (not comparable)[1] Old Galician-Portuguese wrote oonte;[2][3] Houaiss records ontem and otem in 1391 and omtem in the 15th century.[2][3] Barbosa (1611) and Pereira (1697) head the word hontem and refer ontem to it, and Houaiss's first hontem is of 1713.[4][5][3] Silva Bastos (1912) calls hontem the commoner spelling, but notes that the official spelling reform of 1911 made it ontem.[6]
Etymology
It is inherited from Latin ad noctem (“at night, towards night”), the phrase of ad (“to, towards”) and nox (“night”), written Old Galician-Portuguese oonte in the oldest texts.[3][2][7][1] The phrase meant “last night” and so “on the day that ended with last night”, as Nascentes explains it, and he compares amanhã, made in the same way.[7] The DLP starts instead from a longer phrase with heri (“yesterday”) in front, “yesterday at night”.[8] The cantigas still have Old Galician-Portuguese eire “yesterday”, the old word inherited from that Latin adverb, which the new word displaced.[9][1]
Houaiss quotes Nascentes's account of the sound changes: *anoite became *ãoite when the first vowel was nasalised, then *õoite by assimilation and *õote when the semivowel was absorbed; contraction gave onte, still a popular form, and the nasal was at last drawn out at the end of the word.[3][7] Wiktionary gives the same chain through the first two stages.[1]
The same Latin phrase gave Galician onte “yesterday”, while Spanish anoche, Asturian anueiti and Old French anuit kept the sense of the night itself.[10][11][1] The Latin preposition goes back to *ad and *h₂éd (“near, at”), the source of the English word at too.[12][1] The Latin noun is from *nokʷts, from *nókʷts, and is cognate with νύξ (núx) and the English word night.[1]
Earliest recorded meaning
The oldest record that Lorenzo's chronology gives is a cantiga d'escarnho of Pero Garcia Burgales, which tells of something done oonte ao serão “yesterday in the evening”.[13] Cunha dates oonte to the 13th century;[2][3] Houaiss's first dated record is of 1391, with the spellings ontem and otem, already in the sense “on the day before today”.[2][3]
Semantic evolution
Beside “on the day before today”, Houaiss records the extended senses “at some earlier, unspecified time” and “only a short while ago”, and the use as a masculine noun, o ontem, for the day before and for the past.[3] Bluteau (1712–1728) already lists phrases such as ontem pela manhãa “yesterday morning” and ontem de noyte “last night”.[14]
Set phrases include antes de ontem “the day before yesterday”, also written as one word, anteontem;[3][15] de ontem para hoje “overnight, in a rush, all of a sudden”; and para ontem “with the utmost urgency”.[3][15] The original Caldas Aulete records ser nascido ontem “to be young and inexperienced”, and Porto Editora olhar para ontem “to be lost in thought”.[16][17]
The word passed into the creoles: Kabuverdianu has ónti and Macanese onte.[1]
