Hi, Denis!  Recently you wrote in a message to Ardith Hinton:

 DM>  Are You native speaker, Ardith?

 AH>  Yes, I am *a* native speaker of English.  :-)

 DM>  Are You a native speaker, Ardith?


           That's better.

           I realize your dictionaries may be less than helpful here when I see
my Canadian dictionaries don't give any examples of "native" as an adjective in
combination with "a".  But it seems clear to me that in this context both "a" &
"native" are functioning as adjectives modifying the noun "speaker".

           The only other point I have to add WRT this example is to remind you
that even though "I" is capitalized in English, other pronouns aren't.



 DM>  ... You have the capacity to learn from mistakes.


           Indeed.  As I used to tell my students, I try to make my classroom a
safe place for you to experiment with constructions you're not sure about.  :-)
