Forms

esposar (first-person singular present esposo, first-person singular preterite esposei, past participle esposado)[1]

Etymology

It is inherited from Late Latin spōnsō (“to betroth, promise in marriage”).[2][3][1][4] Nascentes considers the word semi-learned, and notes that it replaced Latin nūbō (“to marry”).[4]

The same Latin verb is Spanish esposar, Catalan esposar, Occitan esposar, French épouser and Italian sposare.[5][1] The Latin verb is post-classical: the OLD and Lewis & Short cite it from the Digest, and in Medieval Latin it meant “to marry” and “to marry off”.[6][7][8] It is formed on spōnsus, the past participle of spondeō (“to promise solemnly, pledge”), according to Houaiss; the OLD forms it on spōnsa (“bride”), and Wiktionary allows either.[2][6][1] The French historical dictionary traces spondeō to Proto-Indo-European *spend- (“to pour a libation, promise”), the root of Ancient Greek σπένδω (spéndō).[9]

Earliest recorded meaning

Houaiss's date of 1124 is a Latin legal text with the Romance verb in it, hominem de fora parte que esposar mulier de caualeiro “a man from outside who marries a knight's wife”.[2][10] The first Galician-Portuguese records are of the 13th century, the century Cunha gives: in the Cantigas de Santa Maria a girl's father and mother a foron mui sen seu grad' esposar “betrothed her quite against her will”, and the Fuero Real speaks of a woman esposada “betrothed” but not yet married.[10][3]

Semantic evolution

In the medieval texts the verb means both “to betroth” and “to marry”, and the Crónica Geral uses esposados of a couple who then received the blessing in church the next day.[10] Cardoso (1569) and Pereira (1697) gloss it with Latin despondeo “to promise in marriage”.[11][12] Morais (1789) defines it as the priest's act of marrying the betrothed.[13]

Vieira (1871) adds the figurative sense “to support, sustain”.[14] The old Caldas Aulete quotes Castilho for the poplar that esposa the vines and Rui Barbosa for esposar an agitation, that is, to take up a cause.[15] Cunha gives the sense “to accept an idea, adopt a party” as an extension of the first.[3] In parts of Portugal the verb was recorded for “to court”.[16]
