Irish Translation Forum

Yes, it is Wales not Whales. I'm a bit dislexical sometimes.
I'd like to learn a little about the gaelic. Don't warry, I'm not asking for an academical lesson right now but just for one or two examples.
For instance; how would you pronounce the name of the irish mytholigical hero Cu-chulainn or chu-chulainn? (actually, which is the right orthograph? )

thanks & rgds
