We just learned a few ways to say hello and goodbye in Greek, like Γειά σου (Geiá sou), Χαίρετε (Chairete), and Αντίο (Antío).
Sometimes you might want to say good morning, good afternoon, or good night.
Good Morning/Day - Καλημέρα (Kaliméra) - sounds like kah-lee-may-dah
Good Afternoon/Evening - Καλησπέρα (Kalispéra) - sounds like kah-lee-spay-dah
Good Night - Καληνυχτα (Kalinychta) - sounds like kah-lee-nich-tah
The letters for these words are:
Κ (Kappa) α (alpha) λ (lambda) η (iota) μ (mu) έ (epsilon) ρ (rho) α (alpha)
Κ (Kappa) α (alpha) λ (lambda) η (iota) σ (sigma) π (pi) έ (epsilon) ρ (rho) α (alpha)
Κ (Kappa) α (alpha) λ (lambda) η (iota) ν (nu) υ (upsilon) χ (chi) τ (tau) α (alpha)
