Check the time. Greeks say "kalemera" as a morning greeting, "kalo apoyevma" to say "good afternoon," and "kalespera" to say "good evening."
Try saying "yah su" to greet friends and family. This is a more informal, blunt version of "hello." For a shortened version used among young people, try saying "ya." If you're greeting a group of people, say "yah sas."
Use "ya sas" to say hello to older people or when you want to show deference and politeness.
Opt for different forms of hello when on the telephone. When speaking to friends, use the informal "ela," pronounced "eh-lah," or "embros," pronounced "ehm-bross." Answer the phone at work or in a more formal setting with the greeting "leyete."
Start a conversation by saying hello and then asking how someone's doing. Ask friends and young people by saying "pos ise?" or "te kanis?" (both mean "how are you?"). In formal situations, try "pos iste?" and use "te kenete" to address a group.
