Hi,
I think Mr. M said something to the effect that when two or more nouns are used as a compound noun, there should be no need to hyphenate.
Case I use to ask a question in a previous post:
A pencil that can also be used as an eraser:
I want to have a pencil eraser (or pencil-eraser??).
For this, I think Mr. M said he preferred a non-hyphenated version.
Fine, but how tight a relationship has to be between the nouns used has to be in order to use a hyphen to connect them both?
This might not be a preferred example to use but what is the difference between this and the above?
