Pronunciation
Forms
assumir (first-person singular present assumo, first-person singular preterite assumi, past participle assumido)[1]
Etymology
It is borrowed from Latin assūmō (“to take up, take to oneself”), first recorded in 1690.[2][3][4][1] Nascentes calls it a semi-learned word.[5] The Latin verb is formed from ad- and sūmō (“to take”).[6][1]
Wiktionary analyses the simple verb as sub and emō (“to buy, take”), from Proto-Italic *emō and Proto-Indo-European *h₁em- (“to take”).[1] The same Latin verb is Spanish asumir.[7]
Earliest recorded meaning
Machado and Houaiss take the first record from Manuel Fernandes's Alma Instruída (1690), in a theological sense: God decreed to come down to the state of creatures and unir ou assumir a si alguma natureza creada “to unite or take on himself a created nature”.[4][2] A private letter of the same year writes asumir.[8]
Semantic evolution
Morais (1789) defines it as “to take, attribute to oneself, arrogate”.[9] Vieira records it only as a synonym of consumir in a pharmacopoeia, and notes that the Academy's dictionary lacks it.[10] The original Caldas Aulete has taking on a serious air, from Rebelo da Silva and Camilo, and taking up a high office or power, from Garrett, and gives the irregular participle assunto beside assumido.[11]
Modern Portuguese uses it above all for taking on a responsibility or an office, for acknowledging something as one's own, and, reflexively and informally, for coming out as gay or bisexual.[2][1][12]
