Lexical categories

[Annabelle David]

Hello

I am trying to find a study that would have data on the different
proportions of each lexical category (nouns, predicates, etc) at different
stage of the lexical development process and at the adult stage. I know
CDI-based studies have such results for very young children but I am looking
for data on older children and/or adults in English and French. 

Thank you .
