I am not sure about the the form of the noun after the usage of and in the following case.
1. The Berlin and the Munich city
2. The Berlin and the Munich cities
Which one of the two is correct?
Many thanks for your support.
1. The marginal and the chief ray
or should it be
2. The marginal and the chief rays
I am afraid, the rays of marginal and chief do not sound correct to me.
Yes, use "rays." There are two of them.
Many thanks, bahisahab and soothingdave. I appreciate your support and consideration. Have a nice evening :)
