I was confused by the roles of nouns in English. It seems that nouns can modify verbs as stated in this qeustion and adjectives in these examples:
Do You Know How to Be Street Smart?
... the prior predictive kernel distributions are not orders of magnitude different from the observed data.
I wonder if the two types of nouns act the same role? In the above sentence is
street acting as an adverb? Or something else? When can we modify adjectives with nouns?
