A friend is using the tagline Sure fix for conflicts. He says sure fix needs a hyphen (Sure-fix). I'm not sure. Which is correct and why?
If "sure" is used as an adjective or adverb (the only options Merriam-Webster presents), it is a clear case. It must stay a separate word, and doing otherwise would be wrong.
I cannot find the phrase "sure-fix" in any of my usual dictionaries.
My conclusion: Your friend is misguided from the standard English point of view.
