@kabite & others : How is actually wij spoken ? And how "coel" ?
The "ij" in "wij" is pronounced as the first "e" in "where". In fact, cut the "re" from "where" and you have the correct pronuncation for "wij".
"coel" isn't a word in Dutch... "Koel" is, proncounced as "cool" in English, with the same (original) meaning: something like cold...
