Ancient Greek · noun · Descent
ἔρως
eros
/ˈɪərɒs/ or /ˈɛrɒs/
Passionate desire, and love as longing or striving. Not a synonym of ἀγάπη.
Greek ἔρως is received in Latin, then borrowed into English. Plato can stretch the word from bodies toward beauty and the good. That stretch is reception. The deeper origin of ἐράω is not a secure root.
Morphology Ancient Greek ἔρως, -ωτος, ὁ. Accusative ἔρωτα. Epic and Lyric often prefer the poetic ἔρος. The noun sits with ἐράω / ἔραμαι, ‘to love, desire passionately,’ with a genitive of the person or the thing. Established as a lexical relation. The ultimate origin of the verb is not secure.
Ancient Greek · the noun we have
Passionate desire. The noun sits with ἐράω / ἔραμαι. A secure deeper root is not part of this step.
Latin · reception
Eros2
The Latinized name, and Amor or Cupid as the Roman person. Reception of the god, not a new derivation of the Greek noun.
English · late 14th century–
eros2
The god, then erotic desire, then a Freudian name for the urge.
Senses through time
Homer / early poetry
Love and desire, often sexual passion. Also appetite-desire in formulaic phrases. Epic and Lyric prefer ἔρος.1
Established
Tragedy and classical prose
Love, mostly sexual passion, and also a strong desire for a thing: the fatherland (Aeschylus, Agamemnon 540), good fame (Eumenides 865). Thucydides 6.24 uses ἔρως ἐμπίπτει with an infinitive. Sometimes passionate joy (Sophocles, Ajax 693).1
Established
Plato, Symposium and Phaedrus
Longing that can climb from bodies toward Beauty and the good. A philosophical psychology of desire. Reception, not the only Greek sense.1,2
Established
The god
Ἔρως personified. Sophocles, Antigone 781, opens Ἔρως ἀνίκατε μάχαν. Latin Amor and Cupid are Roman reception of that person, not a second Greek etymology.1,2
Established
English
Late 14th century, the god and (carnal) love. From 1922, the Freudian life or sexual urge. Setting eros against agape, as carnal love against Christian love, is later reception, noted from 1856.2
