In French (and many other languages), adjectives and pronouns have different classes, e.g.:

Adjectives

• demonstrative
• indefinite
• interrogative
• numerical
• possessive

Pronouns

• demonstrative
• indefinite
• interrogative
• personal
• possessive
• relative

I would say that adjectives and pronouns fall under the umbrella of a grammatical category, but I can't think of a way to describe how they are further classified - what is the name of the class of modifiers (as listed)? Unfortunately this is probably a very simple question, but I can't find related terms (for English) even in a intro-level linguistics book like How English Works by Anne Curzan, or through Google.
