  • Portugal: /ẽˈtɐ̃w̃/[1]

Etymology

It is inherited from Vulgar Latin *intunc (“then, at that time”), written Old Galician-Portuguese enton and Old Galician-Portuguese entom in the oldest texts.[2][3][4][1] The Latin form joins the preposition in (“in”) and the adverb tunc (“then, at that moment”).[2][1] Nascentes traces the change through the stages *intun and entam.[5] Houaiss dates the spelling with ⟨om⟩ to the 13th century and the present one to the 15th.[2]

Medieval Portuguese also had Old Galician-Portuguese entonce, from *intunce, from the 13th century.[3] From the 14th century it also had estonce and estõ, from *extunce and extunc.[3][4] The longer form gave Spanish entonces, while the shorter one is Galician entón and Old Spanish enton.[1][4][6]

The Latin adverb comes from an Old Latin form with the particle -ce added to tum (“then”).[7]

Earliest recorded meaning

Galician-Portuguese documents of the 1250s already have the word: entõ o juiz deu sa carta “then the judge gave his letter” (1257) and enton o Juiz chamou ante sy os omees desses lugares “then the judge called before him the men of those places” (1258–1261).[8] The satirical cantigas have it in a vaca morreu-xe logu’ enton “the cow died right then”, and the Cantigas de Santa Maria have both enton and entonce.[8][9]

Semantic evolution

Barbosa in 1611 glosses it with Latin tunc and notes that it is said of present, past and future time.[10] Morais in 1813 gives the senses “at that time”, “on that occasion” and “in that case”, and notes its use as the correlative of quando.[11]

From “in that case” the word developed a conclusive sense, “so, therefore”, and it is also used as an interjection of surprise, doubt, impatience or encouragement, and in questions such as e então? “and so?”.[12][13][14] Popular variants are antão, atão and intão.[15][16][17]
