Pronunciation

Forms

tieso (feminine tiesa, masculine plural tiesos, feminine plural tiesas)[1] Old Spanish teso; the diphthong appears in 1570.[2][3] Autoridades spells it tiesso.[4]

Etymology

It is inherited from Old Spanish teso, inherited from Vulgar Latin *tēsus, from Latin tēnsus (“stretched, taut”), the past participle of tendō (“to stretch”).[2][3][5][1][6] The diphthong is a late change made under the influence of tender and its diphthongised present forms.[2][3][7][8] Because of it, Meyer-Lübke at first refused the derivation that Diez had proposed, and Baist proposed tersus (“smooth, clean”);[2][7] García de Diego persuaded Meyer-Lübke of the error, and Corominas calls this etymon impossible in sense and in sound, since the old sources spell the word with a voiced /z/.[2][7] The learned doublet is tenso, from the 19th century.[6][1]

The undiphthongised form survives in Portuguese teso, Galician teso and Catalan tes, beside Asturian tiesu;[7][9] García de Diego also cites Aragonese tiesse from old Aragonese texts.[7][9][10] The Latin participle is a later, analogical form of tentus, from Proto-Indo-European *ten-d(h)- (“to stretch”).[1][11]

Earliest recorded meaning

The Old Spanish teso is first recorded in the 14th-century Sumas de historia troyana, and later in the Rimado de Palacio.[2][1] DEMel lists the word in the glossary of an edition of the Libro del Tesoro (late 13th century).[12] Corominas's first tieso with the diphthong is in Cristóbal de las Casas's Spanish–Italian vocabulary of 1570.[2][1]

Semantic evolution

Teso still meant “taut, tight” in Alfonso de Palencia's vocabulary, and it survives in that sense as a nautical term and in Asturias and Cuba.[7][2] In the Quijote tieso is used of stiff legs on horseback, of a strong, sinewy woman, and in tenérselas tiesas, to stand up firmly to someone.[13] In 1534 tierra tiesa “firm ground” is recorded in Puebla.[14]

The Diccionario de Autoridades (1739) gave “hard, firm, not easily bent”, “robust, especially after an illness”, “brave”, “stubborn”, “excessively grave and circumspect” and the adverb in pisar tieso.[4] The Academy added “taut” and tieso que tieso for stubbornness in 1817.[15] The colloquial senses “dead”, “astonished”, “stiff with cold” and “broke” are in the current DLE.[5] In the Americas it means “very drunk” in Peru, “boastfully brave” in Ecuador, “brave” in Honduras, “skilful” in Chile and “stingy” in Nicaragua.[16] In Andalusia tieso is also steep mountain ground.[17]
