Etymology

It is inherited from Proto-Italic *ama- (“to take, hold”), inherited from Proto-Indo-European *h₃mh₃- (“to take hold of”).[2][1] The meaning would have moved from “to take someone's hand” to “to regard as a friend”.[2] Schrijver argues from its stative meaning and the noun amor that it was once a stative verb.[2][1] The OLD calls the origin doubtful.[3]

Cognate with Marrucinian amatens (“they have received”),[2] Old Irish námae (“enemy”) and Ancient Greek ὄμνυμι (ómnumi, “to swear”).[2]

Earliest recorded meaning

It is found from Naevius onwards,[2] whose character says “I don't want to love her so desperately”.[3]

Semantic evolution

It meant to love or be in love, and also to make love or to caress.[3] It covered affection for family and friends, and regard for public men, as in Ennius' “the good orator is scorned, the rough soldier loved”.[3] Gods were said to love, that is, to favour, people.[3]

It also meant to enjoy something or delight in it, and amo te was a way of saying “thank you”, as in Plautus and Cicero.[3] Amabo, “I shall love you”, meant “please”.[1] In poetry and later prose things were said to “like” certain conditions, and with an infinitive it meant to be wont to do something.[3] It survives as Italian amare, French aimer, and Spanish and Portuguese amar.[1] English amateur came in 1784 from French, from its agent noun amator.[4]
