Hi all
I want to ask about what is meant by Lexico-grammatical?
Comments 
It means a combination of vocabulary (lexus) and grammar. It is a term which is intended to be comprehensive for the make-up of an utterance, though it does not include extra-linguistic factors such as tone and gesture.
could you please, give example
where can i find some sources about the definition of lexicogramaatical features??
I found some information via a simple Google search. Have you tried that?
