Pronunciation

  • /asuˈmiɾ/, [a.suˈmiɾ][1]

Forms

asumir (first-person singular present asumo, first-person singular preterite asumí, past participle asumido)[1]

Etymology

It is borrowed from Latin assūmō (“to take up, take to oneself, adopt”), a learned word.[2][3][4][1] The Latin verb is formed from ad- and sūmō (“to take”),[1][5] itself formed from sub- and emō.[5][6]

The simple Latin verb gave Spanish, by a popular route, sumir.[2] Learned words of the same family are asunción (early 15th century) and asunto (an adjective in the first half of the 15th century, a noun in the Quijote), from assūmptiō and the participle assūmptus.[2][3]

The sense “to suppose, take for granted”, common in Latin America, is from English assume.[7][8]

Earliest recorded meaning

Alonso's first quotation is from a translation of Boccaccio's Mujeres ilustres (1494, quoted from the edition of 1528): Perseo, que después fue assumido en el cielo “Perseus, who was afterwards taken up into heaven”.[9] Corominas dates the word from 1528.[2][3] The DEMel lists a record in Berceo from a secondary source.[10]

Semantic evolution

Autoridades called assumir “to take, draw to oneself” an obsolete word of the Aragonese dialect, quoting the Fueros of Aragon.[11] The Academy's 1770 edition added a quotation from a Spanish version of Saint Ambrose's De officiis and kept the Aragonese legal use “to bring a case before oneself”,[12] which the 1884 edition still lists as a legal sense.[13] Borao recorded the verb in Aragon too.[14]

In the Americas it is recorded from 1575 in Mexico, of captives taken up into the house of the sun.[15] A Nicaraguan text of 1865 uses it of states assuming their full sovereignty.[15] The modern central sense is to take on a duty, office or responsibility, and to accept a hard fact.[4][16][17] Judeo-Spanish has asumir una tareja “to take on a task”.[18] The sense “to suppose” is used in Mexico, Central America, Puerto Rico, Colombia, Chile and Argentina.[7]
