I've always wondered why some people add a
Why when framing a question. I have always wished to know this, but I keep forgetting to ask and today I came across a tweet that made me post this question here. The sentence that I came across on my twitter feed is:
Why To Treat Your Product Like It's Finished?
Isn't it more appropriate to ask:
Why Treat Your Product Like It's Finished?
I know that all the words in the sentence above have a capital letter in front because this was a title of a post. But that is not the point.
My question is: When do we need to use a preposition like
to after a question word like
Why? Are there any grammatical rules regarding this usage? If so, what are they?
