As compared to "verbal communication" or "visual communication", I was wondering if there was a synonym for "written communication" that is semantically similar to the first two. What throws me off is that written is both a verb and an adjective, while verbal and visual are singularly adjectives. Is this a distinction I should even worry about?
Don't worry about what part of speech these three words are for two reasons:
First, verbal is a noun as well as an adjective;
Second, it doesn't matter what part of speech they are but how they are used.
If you have an example sentence that might confuse a reader or listener, please provide, though.
I think Textual communication is the officially accepted equivalent.
