Could you plz tell me it is wrong or right? Thx so much.
" I believe this will be a mutually rewarding and long-lasting relationship."

I learnt it from a book that the both sides of the word 'and' must be the same word class. So here, should there is a noun before the ' and'?

Thank you.

Answer

The words on either side of the 'and' are the same word class -  'rewarding' and 'long-lasting' are both adjectives. The relationship will be both mutually rewarding and long-lasting.
