From the same root
Forms
tanto (feminine tanta, masculine plural tantos, feminine plural tantas)[1] Medieval texts also write tãto, tant' before a vowel, and the longer atanto.[2][3]
Etymology
It is inherited from Latin tantus (“so great”), written Old Galician-Portuguese tanto in the oldest texts.[2][3][1] Already in Vulgar Latin it was also used for “so many”, and it took the place of tot (“so many”).[4][5]
The same Latin word is Galician tanto, Spanish tanto, Catalan tant, French tant and Italian tanto.[6][1]
The Latin adjective is formed from tam (“so”), like quantus beside quam.[7][1] De Vaan reconstructs *tānto- and thinks it probably continues an inherited type of adjectives with the suffix *-nt- built on pronoun stems.[8][8]
The adverb tão may come directly from the Latin adverb or be a shortened form of this word before the word it qualifies: Cunha gives both possibilities, and Corominas leaves the question open for Spanish tan.[3][9]
Earliest recorded meaning
Houaiss and Cunha date the adverb and the pronoun to the 13th century.[2][3] In the cantigas the word is already an adjective “so great, such”, the correlative of quanto, an adverb “so hard”, and a noun in tẽer en tanto “to hold in such esteem”;[10] mil tanto means “a thousand times as much”.[10] The Crónica Troiana speaks of men so many (tantos) that they could enter the land.[10]
Semantic evolution
Bluteau (1712–1728) glosses the adjective as “so great” and explains how it is put into Latin.[11] Folqman (1755) records outro tanto “as much again”.[12] Houaiss dates tanto melhor “so much the better” to the 14th century.[2]
The noun came to mean an indeterminate amount and “times” in comparisons (três tantos “three times as much”), and in the plural it stands for a number that is not given (trinta e tantos “thirty-odd”).[2][4] In Portuguese dialects tanto is also used for tão before an adjective.[13]
