I was just curious. I learned my grammar in Catholic schools in the 60s and 70s, which I guess is before the dawn of modern linguistics!
Your points make a lot of sense. My thought was that determiners describe and modify nouns just as adjectives do. This is probably why, in ancient linguistics, articles and other determiners were adjectives.
By "some pronouns function as adjectives" I meant the following (please forgive if I use the wrong title; it has been 45 years since Catholic school):
Possesive pronouns (eg, my etc), object pronouns (mine etc), demonstrative pronouns (this etc).
I was taught that those are pronouns that function as adjectives. Based on what you have said, it seems that demonstratives can function as adjective or determiner (this book/ i want this). Possessive pronouns only functionas adjectives (my book). Object pronouns only function as determiners (It is mine.)(or would that be called a predicate adjective?)
Im just returning to grammar after 40 years away so forgive my ignorance. Based on what you hace said and what i have read, the case for deteeminers being classified as a part of speech, not a subclass of adjectives makes sense.
Could I logically say, then, that adverbs, adjectives, and determiners are all modifiers?
Thank you so much for your time. If you are inclined to respond back to my new queries, I would appreciate it!
