Thank you so much for your response. I was without electricity for a few days so i could not respond sooner. I am impressed with your knowledge given that english is not your first language!
I will have to modernize my thoughts and add determiners as a part of speech.
As for the pronoun issue, I was taught as follows.
Possessive pronouns: my, your, his, her, its, our, your, their
also anybody's, anyone's, someone's, nobodyx s, no one's, one another's, each other's.
Demonstrative pronouns: this,that, these, those
(Also subject, object, possessive object, relative, reciprocal, reflexive, interrogative, indefinite...but that's another discussion!)
So i was taught that when you use a possesive or demonstrative to describe a noun, that pronoun functions as an adjective. I will now correct my understanding to say that these pronouns function as determiners. The technical reasons why make sense, but it is hard to get used to!
I will ask about articles soon!
