"AID" is pretty much alway's pronounced like "age", except when there is a "h" after it. Then it is said "Ai"
"C", except in ch, is almost alway's a "k" (there is no k in the gaidhlig alphabet). So "Caraid" (friend) is pronounced "Car-age"
"I" is alway's "ee", and is the gaidhlig for "her"
"E" is always said in its "eh" form and is the gaidlig for "Him"
Hope the capitals don't confuse you.
