I was at one of Stack Exchange's many forums, and I came across a question that made wonder on whether I was building a sentence correctly when using the word "Why", and if that new way was right.
How I would write it:
"Why not to use a cotton base layer?"
How I saw it written:
"Why not use a cotton base layer?"
My question is, which sentence is correct, why, and if both, are they interchangeable?
