  • IPA (Ecclesiastical): [aˈdɔp.to][1]

Forms

adoptō (present infinitive adoptāre, perfect active adoptāvī, supine adoptātum); first conjugation[1]

Etymology

It is from ad- “to” and optō “to choose”.[2][1][3][4] The TLL notes that it was in use from Plautus through all Latin.[3] An inscription has ⟨atoptetur⟩.[2]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, of choosing someone as an ally, as his sociam tē mihi adoptō “I choose you as my partner”.[2][5] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

It meant to take to oneself in some role, choose as an ally or protector, as Cicero's defender of one's rights.[2][7] From Terence it meant to adopt legally, usually as a son, in Horace jokingly as a father or sister, and in Ovid of grafting.[2] In Plautus it meant to bring into a position by adoption, and in Pliny the Elder reflexively to join.[2] In Seneca it meant to take over, assume, in Vitruvius a name, and in Pliny the Elder to name a thing after oneself.[2]

In Ecclesiastical Latin it meant to choose, select, adopt.[8] It was borrowed into French adopter and Spanish adoptar, and English adopt came about 1500, “to make one's own by selection”.[1][4]
