***** NOT A TEACHER *****
Hello, Yura Reiri:
(1) I found a good explanation in Random House Webster's Unabridged
Dictionary (2001). For copyright reasons, I am going to use my own

James (begins to cry): I'm stupid, aren't I!!!
Teacher: No, no!!! The usage of nouns is not an easy matter. ( = the
traditional ways in which native speakers use nouns are not easy for
a learner to understand.)
