It would be helpful for a modern Gk speaker to give a brief overview of the different nuances of the verbs for love in Gk. The ancient Gks, of course, had several words for love and they could be used in distinct ways even as there was some overlap and not complete consistency.
The verbs φιλέω and ἀγαπάω and στοργέω (esp. love of parents and children, familial love) and ἐράω (and έράομαι or ἔραμαι), and the corresponding nouns such as στοργή (intimate affection among people brought up together), φιλία (which can refer to friendship), and ἐραστής, "lover." Someone noted that φιλέω can mean to kiss in modern Gk, which is interesting because that is a sense in ancient Gk as well depending on context. Love terminology is particularly a problem for English speakers because we only have one word, whether noun or verb, to love, and so when we want or need to differentiate types of love we must use an adjective (agapic love, erotic love, familial love, friendship love). A key moment in the rich love terminology in Gk history was when Christians tied agapic love (a) to God with great emphasis in texts such as 1 John 4 and (b) in ethical teachings regarding love of enemy in what scholars refer to as Q material (Luke 6:31 // Matt 5:33-34). Much has been written about all of these verbs and nouns before Christianity came on the scene and the effects that Christian emphases had on the terms, what Christians inherited and how different authors negotiated these terms in their own ways. Paul's hymn to agapic love in 1 Corinthians 13 is often placed in context with Plato's paeon to Eros (erotic love) and Philia (friendship) in Lysis and the Symposium (to some extent in Phaedrus). Here's an online academic overview of that topic in Plato: https://plato.stanford.edu/entries/plato-friendship/ But here's an overview by someone who succinctly summarizes key aspects: https://windycitygreek.com/ancient-greeks-7-ways-fall-love/
