Have you tried working through the Grammar Glossary? http://www.usingenglish.com/glossary.html
Mi question is, where and when a word become token or type and what is the difference?
Can you tell me where I can find information about words (families. classes, formation, multi units) Lexical fields and style and collocation?
Thankyou in advance for your support.
Yes I have, but there is not enough information about that.
With reference to token and type see : type-token ratio - Encyclopedia.com
lexical fields = Lexical field theory - Wikipedia, the free encyclopedia
word families = Word Families Sound Alike and Look Alike
collocations = Collocations for ESL teachers: eslflow webguide
That should keep you busy for a while!
