where can i find a list of prenominal and postnominal adjectives?

Question

and how can find some grammar rules to differentiate between them??

Answer 1

In English? There are *only* prenominal adjectives.

Answer 2

Words such as everything, anything, something, nothing, and so on, have a certain rule to adjectives. You will find that "every", "any", "some", and "no" occupy the position of article or adjective originally. That is, for example, "John got something special." In this sentence, "something" is a compound word for "some" and "thing." When we combine them into ONE word, there is no room for any adjectives-- we cannot posit any adjective before "something" -- "some" has to precede adjectives--, cannot even insert as "somespecialthing." Therefore, "something special."

Some words referring "anything" are also with pronominal adjectives, such as "elements unknown."

Answer 3

This is a really tough question. With some exceptions for poetry and borrowing from other languages, postnominal adjective only occur with indefinite pronouns. Indefinite pronouns are words like everything, something, anything, everyone, everybody, nobody, . . .

Some examples.

"I saw EVERYTHING INTERESTING that there was to see in the museum in five minutes."

"She said that Bob was NOBODY IMPORTANT."

"My boyfriend took me SOMEPLACE SPECIAL on our date."

I can't really state the rules, as there may be lots of weird exceptions, but if you don't know if a combination is acceptable, try searching for it in quotes on Google. If it's unacceptable (incorrect), it will yield very few hits, if any.
