Pronoun
Definition:
the word 'all' can be used as a pronoun, which indicates the number or quantity of a certain thing or set of things, independent of any other thing. For example, 'all of the food' implies the entire amount of the food or that all of the food is considered as a whole unit -- not in parts. When used as a pronoun, 'all' is used without an article (like 'the') preceding it.
Examples:
1. All these books are mine.
2. They took all of the money.
3. We need to find a place with room for all of us.
Tips:
it is uncommon to use 'all' as a pronoun in informal writing, so it is generally preferred to use 'everything' or 'whole' to emphasize the idea that something is considered as a whole.

Examples:

Tips:
the placement of 'all' can change the emphasis in a sentence. For instance, 'I all but confirmed the news' means 'I did everything except confirm the news.' Avoid redundancy. For instance, 'all the entire time' is redundant; use 'all the time' or 'the entire time.'
