Ok guys!! I've just checked the glossary provided by Wiki. This is going to help me! I have just to copy those expressions into a txt file and put it into wordsmith.
By the way, do you know if there are other (good and professional) sites where i can get othere idioms?
Guys I thank you, you've been nice to me! And this site is wonderful, a great source of information for linguistics! You guys are great!!
