I am trying to learn Irish from a CD program and they have I'm very glad to meet you as "Tá an-áthas orm bualadh leat." and It was nice meeting you. as "Ba dheas casadh leat." My question is why is bualadh ([to] hit) used in the first statement instead of casadh ([to] meet)? Could the first statement be "Tá an-áthas orm casadh leat."? Also I have seen maith meaning good and forgive but in the dictionary math ment good. could someone please explain this to me.
Thanks
