I have to know if these Demonstratives are Adjectives or Pronouns."These belong to the girl who lives next door" "This aisle contains what susan wants." "That ship has been docked for three days." I have them as pronoun and 2 adjectives. Is that right?

These books = here is an example of the demonstrative adjective

BUT
These (standing in for both the adjective and the noun) is an example of a pronoun.

This aisle = adjective (modifies a noun)

That ship = adjective (modifies a n oun)

Yes, you are right!
