how to say hello in greek

The most common way to say "hello" in Greek is "γεια σας" (YAH-sas) in formal situations, or simply "γεια" (YAH) in casual settings. This greeting is used throughout the day and can also mean "goodbye." For a more informal hello, "γεια σου" (YAH-soo) is used when addressing one person, while "γεια σας" (YAH-sas) is for plural or formal situations. Additionally, Greeks use time- specific greetings such as "καλημέρα" (kalimera) for "good morning," "καλησπέρα" (kalispera) for "good afternoon/evening," and "καληνύχτα" (kalinihta) for "good night".
