Edit: 12/01/09: Asked one of the English teachers I work with today and she said that ゆう is Kansai-ben for 言う。
言う (iu; to say) is a word that you learn fairly early on in Japanese studies. Being an ~う verb, the ~て form (used for commands and a slew of other grammatical constructions) is, of course, 言って. However I've noticed that sometimes Japanese people will say いうて instead. I'm wondering if this is just a spoken variation or some special rule I haven't encountered in my studies.
Anyone know anything about this one?
