How do you say how are doing in greek?

There isn't one single perfect translation for "How are you doing?" in Greek, as the best choice depends on the context and your relationship with the person you're talking to. Here are a few options:

* Τι κάνεις; (Ti kaneis?) - This is the most common and versatile way to say "How are you?" or "What are you doing?" It's informal and suitable for friends and family.

* Τι κάνετε; (Ti kanete?) - This is the polite form, used when addressing someone older, someone you don't know well, or multiple people. The ending changes to show the plural.

* Πώς περνάς; (Pos pernas?) - This translates more literally to "How are you passing (your time)?" It's informal and implies a more personal inquiry about well-being.

* Πώς τα πας; (Pos ta pas?) - Similar to the above, but even more informal. It literally translates to "How are you going (with things)?"

Therefore, Τι κάνεις; or Τι κάνετε; are generally safe and appropriate choices in most situations. The others offer slightly different nuances.
