My wife is learning english from a teacher who uses a german text book, which I think is stupid but my wife likes the teacher. Sadly her dominican education did not include grammar. Is there an easy and foolproof way of getting her to understand the difference and use of pronoun, third person singular( which nearly always takes an "s" added to the infinitive) seeing that she does not know the word infinitive!? The other problem is pronunciation, seeing that many dominicans either don't pronounce an "s" such as pecados instead of pescados and want to put a "e" in front of any word beginning with "s". Such as "e"ship or "e"stephanie. The " first shall be last" comes out of her mouth as "the fur eshall be laa". Any bright ideas anybody??
