When you refer to a generalized part of a generalized plural noun, should I use "a part" or "parts"?
do you have to use " city names" as "a part/parts" of " commercial addresses"?
This is the only example I could come up with using the "generalized part of a generalized plural noun" formula, so if you have better examples, please help!
EDIT:
Can you help me with the example below, where plural nouns should be used (or at least I think they should be used in this context)?
Please use color names as a part/parts of design titles?
It sounds weird to me, but I can't pinpoint why . Am I misusing plural nouns in this case?
