(1) "μπορεί equals I may and it is the same as πρέπει whereas the verb doesn't change id singular or plural. I may go to school tomorrow. Μπορεί να πάω στο σχολείο αύριο." Yes, you're right, BUT μπορεί does NOT equal 'must'(πρέπει). In the way you're using it here, it means 'may', or "maybe", as you very well said. (2) "μπορούσα means I could which is the past tense if I can μπορώ. I could go to school tomorrow. Μπορούσα να πάω στο σχολείο αύριο. He could go to school tomorrow. Μπορούσε να πάω στο σχολείο αύριο." Yes, but to correct your examle: Μπορούσα να πάω σχολείο χτες (I could have gone to school yesterday [but I didn't]) Μπορούσε να πάει σχολείο χτες (he could have gone to school yesterday) Μπορούσα να διαβάζω όταν ήμουνα έξι χρονών (I was able to read when I was six) If you use 'μπορούσα, μπορούσε...' etc, you're referring to the past, not the future. Mainly for past ability. (3) "How would you say? I could have gone to school yesterday" As mentioned above: Μπορούσα να πάω σχολείο χτες OR better: μπορούσα να είχα πάει σχολείο χτες (4) "I did a google search of Θα μπορούσα and it should some hits. Is this actually a word." Yes, it is a word! It means 'I could' but for the future (either as a future possibility, or as a polite request, exactly as 'could' is used in English). For example: Θα μπορούσα να πάω σχολείο αύριο ==> I could go to school tomorrow (=it's possible) Θα μπορούσες να με βοηθήσεις; ==> Could you help me out? (polite request) Θα μπορούσα να σε πάω στο σχολείο με το αμάξι. ==> I could take you to school with the car (polite suggestion) (5) "Lastly, do they ever say just I will in Greek and if so do you just say θα. For example, Who will take me to the store? θα (I will)" Yep. You just add 'θα' in front of the verb and it is exactly the same as 'will'. Ποιος θα με πάει στο μαγαζί; (who will take me to the store?) :))
