Indefinite pronouns are words that refer to nonspecific people, places, or things. They typically stand alone and don't need a noun to complete their meaning.
Examples of Indefinite Pronouns:
* Someone
* Anything
* Everybody
* Nobody
* All
* Some
* Many
Here's why indefinite pronouns usually don't come before nouns:
* They are already complete: They express a general or nonspecific idea without requiring a noun to clarify.
* Redundancy: Placing an indefinite pronoun before a noun would create unnecessary redundancy. For example, "some apples" is grammatically correct, but "some the apples" is not.
Exceptions:
* Some indefinite pronouns can be used as adjectives: For example, "some" can act as an adjective modifying a noun.
* "I ate some cookies." (Some modifies "cookies")
* Certain idiomatic expressions: There are rare cases where an indefinite pronoun might appear before a noun in a specific phrase or idiom.
* "All the world's a stage." (This is an idiom, not a regular grammatical construction)
In general, it's best to avoid placing indefinite pronouns before nouns, as it often results in incorrect or awkward phrasing.
