yeah i was wondering about how many times it would actually fail if you just based it on the starting letter, but couldn't think of many words where it doesn't, though knowing english, there is probably many of them.

a regular expression preg_match() looking for the string starting with a vowel as a condition inside an if() statement would provide flow for "an" and an else {} for any other result ("a") would probably do it. don't have time to work out the regexp to use but.
