Yes, the plural form is necessary if they are two separate groups. (that is A group and B group)If I say "A and B groups", is the plural form neccessary for "group"?
For nouns there is a singular form and a plural form (usually).Thank you.
Btw, why is "the" needed here? I am trying to use articles correctly but fail many times. I think the "plural form" is neither specific nor does it belong to the group of nouns in which "the" is required.
further to what Raymott saidThank you.
