Hello everyone, I have been learning Greek for a couple of years but still can not fix the difference between τι and ποιος when they are used in questions for specifying a noun that follows. Here are examples: 1. τι δουλεια κανεις; 2. τι ημερομηνια εχουμε σημερα; 3. σε ποιο ετος εισαι; 4. ποιο ειναι το επωνυμο σας; In my native language τι and ποιος would be translated using one pronoun, it seems the same for English too: 1. what date is today? 3. what year are you in? (about studies) So, could someone clarify the rule when I should use τι and when ποιος is these kind of questions. Thank you in advance.
