I have a question that I was unable to answer today.
Adjectives go before a noun. However when it's a question why can the adjective go after a noun?
Is your teacher Australian? (teacher is a noun and Australian is an adjective, it doesn't follow the rule).
Instead: Are you a good student? (this seems to follow the rule of adjective before a noun)
I'd really appreciate a simple clear explanation.
Thank you in advance.
