How do you say the alphabet in greek?

The Greek alphabet is recited slightly differently than the English alphabet, as there's no single, universally accepted pronunciation for each letter. Pronunciation varies regionally and even between individuals. However, a common pronunciation used in modern Greek is:

Άλφα (Alfa), Βήτα (Víta), Γάμμα (Gáma), Δέλτα (Défta), Έψιλον (Épsilon), Ζήτα (Zíta), Ήτα (Íta), Θήτα (Thíta), Ιώτα (Ióta), Κάππα (Kápa), Λάμδα (Lámda), Μι (Mi), Νι (Ni), Ξι (Xi), Όμικρον (Ómikron), Πι (Pi), Ρω (Ro), Σίγμα (Sígma), Ταυ (Tav), Ύψιλον (Ípsilon), Φι (Fi), Χι (Chi), Ψι (Psi), Ωμέγα (Omégа)

Note that the pronunciation of some letters, particularly the vowels, can vary depending on accent and context.
