* Indefinite Adjective: This is the most common use. It refers to the whole quantity or number of something.
* Distributive Adjective: When used with singular nouns, "all" indicates that something applies to every single member of a group.
* Quantitative Adjective: When used with countable nouns, "all" indicates the entirety of something.
* Demonstrative Adjective: In some cases, "all" can act as a demonstrative adjective, similar to "this" or "that", pointing to a specific group or quantity.
Here are some examples to illustrate:
Indefinite: "All the students went to the library." (refers to the whole group of students)
Distributive: "All dogs bark." (applies to every single dog)
Quantitative: "All five of us went to the party." (refers to the entire number of people)
Demonstrative: "All that glitters is not gold." (refers to a specific group of things that glitter)
It's important to note that "all" can also function as a pronoun, as in "All are welcome." In this case, it stands in for a noun.
