Forms

tibio (feminine tibia, masculine plural tibios, feminine plural tibias)[1] Old Spanish also had tebio, the form of the Leonese manuscript O of the Libro de Alexandre; manuscript P has tibio.[2]

Etymology

It is inherited from Old Spanish tibio, inherited from Latin tepidus (“lukewarm”).[2][3][4][1] The same Latin adjective gave Portuguese tíbio, Galician tibo, Catalan tebi, Occitan tebe, French tiède and Italian tepido.[5][6][7]

The Latin adjective is formed from tepeō (“to be warm”) with the suffix -idus.[8][1] The verb goes back to Proto-Italic *tep-ē- (“to be warm”) and Proto-Indo-European *t(e)p-eh₁- (“to be warm”), a root with cognates in Celtic, Indo-Iranian and Slavic.[9]

The Latin vowel was a short /e/, and Corominas explains the ⟨i⟩ of the Spanish word as the result of that vowel under the influence of the yod in the next syllable.[2][3] In his account the word kept two syllables after the stress, with the diphthong /je/, until late (perhaps about 1000); only then did the yod form and the diphthong reduce to /i/, a simplification he compares with Dieos becoming Dios.[2] He rejects Menéndez Pidal's reconstruction with a long second vowel and Malkiel's *tepius, and notes that the Portuguese form is regular.[2]

Earliest recorded meaning

Corominas's first record is in the Libro de Alexandre (about 1250), describing a spring that was cold by day in the heat and warm at night in the hardest frost: de día era fría, quando faze calura, / tebia era de noche, a la mayor friúra.[2][3] The sense is the physical one, “moderately warm”, which Alfonso X's Lapidario also uses.[10][11]

Semantic evolution

The figurative sense, “slack, lacking fervour”, appears in Alfonso X's General estoria (1280), which speaks of the coraçon tibio of a foolish man.[10] The Diccionario de Autoridades gives both senses, the moral one with a quotation about those who serve God half-heartedly.[12] Terreros added that the word is used of spiritual and moral things, as in una amistad tibia “a lukewarm friendship”.[13]

Today the second sense covers indifference and coolness between people as well as weak faith.[4][14] Colloquial phrases are poner tibio a alguien “to run someone down” and ponerse tibio “to get very dirty” or “to eat one's fill”.[4][14] In Colombia the adjective meant “angry, irritated” (Alemany, 1917); in El Salvador it means “somewhat annoyed”, and in Peru it is used of a person who is badly wounded.[15][16]
