Pronunciation

  • /adoɾˈmiɾ/, [a.ð̞oɾˈmiɾ][1]

Forms

adormir (first-person singular present aduermo, first-person singular preterite adormí, past participle adormido)[1] Old Spanish had the preterite adurmió and the spelling adormjr; the stem vowel becomes ue in the present, as in aduermo, aduerma.[2][3][4]

Etymology

It is inherited from Late Latin addormiō (“to fall asleep”), formed from ad (“to”) and dormiō (“to sleep”).[5][1][6] The Latin verb is found in Caelius Aurelianus.[1][6] The same verb is Portuguese adormir, Catalan adormir, Old French adormir, Italian addormire and Romanian adormi.[7][8][1] Nascentes considers the Portuguese verb semi-learned.[9]

The simple Latin verb goes back to Proto-Italic *dormiō and Proto-Indo-European *drem- (“to sleep”).[10][1] Its cognates are дрѣмати (drěmati, “to doze”) and δαρθάνω (darthánō, “to fall asleep”).[10][1]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) has it in the sense “to fall asleep”: un sueño·l' priso dulce, tan bien se adurmió “a sweet sleep came over him, so soundly did he fall asleep”.[3][2] A Mozarabic kharja of the 11th or 12th century already has adormes.[11][2]

Semantic evolution

The Historical Dictionary notes that until the mid-17th century adormir alternated with dormir in every use, and that from the 18th century on it is mostly literary, nearly always in verse.[2] Alfonso X's prose uses it for “to put to sleep”, “to begin to fall asleep” and “to grow numb”.[12] The Academy called the verb obsolete from 1770 to 1832, but it has been listed without that label since.[2][13] In the Americas it lived on in rural speech: Henríquez Ureña recorded it in Mexico as a mere doublet of dormir, and in Cuba it was called common among ordinary people.[2] The name of the opium poppy, adormidera, comes from this verb, because of the plant's narcotic power.[14]
