Forms

teso (feminine tesa, masculine plural tesos, feminine plural tesas)[1] Houaiss records tesso in the 15th century, and a private letter of 1714 spells it tezo.[2][3]

Etymology

It is inherited from Latin tēnsus (“stretched”), the past participle of tendō (“to stretch, extend”).[2][4][5][1] It is the popular form beside the learned tenso.[2][4][1] The participle is a later, analogical form beside the older tentus.[1]

The same Latin word is Galician teso, Spanish tieso, Catalan tes and Italian teso.[6][7][1] García de Diego explains the diphthong of the Spanish word by the vowel of tender (“to stretch”).[6]

The noun “steep hill, hilltop” has the same origin: Houaiss explains it as a shortening of the phrase ⟨monte teso⟩ “very steep hill”, and Aurélio derives it from the same phrase.[2][8]

Earliest recorded meaning

A Latin charter of 1107, quoted in Lorenzo's chronology, already has the Romance participle: et in anplo habet IIIes cubitos tesos “and in width it has three cubits, stretched”.[9] Houaiss and Cunha date the Portuguese adjective to the 14th century, in the sense “stretched, taut”.[2][4] The noun “steep hill” follows in 1552.[2]

Semantic evolution

From “stretched” the adjective came to mean “stiff, rigid” and “motionless”, then “hard, firm” and, of people, “bold, unyielding”.[2] Bluteau (1712–1728) records it of strong winds and of rivers running fast, and Morais (1789) of rain falling hard and of a man who is brave and firm in his opinion.[10][11] Vieira quotes João de Barros for water that runs tão teso “so strongly”, and records o mais teso do exercito, the strongest part of an army, a use Houaiss also gives for the thick of a crowd.[12][2]

The informal sense “penniless, broke” is used in Portugal and in Brazil, where it is recorded in Paraíba and Rio Grande do Sul.[2][13][14] Portuguese has the phrase ficar teso “to be left without money”.[15] The noun took regional senses in Brazil: in Amazonia a stretch of ground above the level of a flooded plain (from 1899), on Marajó a mound raised in marshy land for houses or burials, and in Rio Grande do Sul the high ground along a river bank.[2][8]
