possessive pronouns

If a possessive pronouns is used as a possessive adjective, (…his book) is it still a pronoun and an adjective, or is it only an adjective and no longer a pronoun.

Hi,

To my simple mind a pronoun is a pronoun and an adjective is an adjective.

In that case, what is “which” here?

Which books?

How about here?

Mary was happy when I asked her.
Mary was happy when I asked her mother.

adjective pronoun = a pronoun behaving adjectivally. The form is pronoun and the function adjective.

Or:

  1. Adjective pronouns, words, primarily adjectives, [color=brown]which are classed as adjectives when they modify nouns, but as pronouns when they stand for nouns.

But:

“Hence these words are like adjectives used as nouns, which we have seen in such expressions as, “The dead are there;” that is, a word, in order to be an adjective pronoun, [color=brown]must not modify any word, expressed or understood. It must come under the requirement of pronouns, and stand for a noun.”

Isn’t there a contradiction with the brown parts above?
