What does “おあい できて うれしい です。” mean??
the dictionary form of あい is あう which means “meet”
できて is できる which means “can”
うれしい is “grad”
です is “be-verb”
おあい できて うれしい です literally means “I am grad to be able to meet you.”
So おあい できて うれしい です means “Nice to meet you”
お before あい is a polite form which you don’t need to worry about the explanation for now.
