Is there a difference in overthinking, over thinking and over-thinking?

I think the right words are overthinking and over-thinking. Over thinking is not right at all. There are no differences between overthinking and over-thinking.

Mimishu is right. “over thinking” is 2 words. I prefer sleep over thinking.

You might be over-thinking this. I have abandoned that. I am SO over thinking.

Dictionary.com does not recognize overthinking as a word. Ineterstingly enough, when you look up overthink, overthinking shows up as a form of the word.

@dxs but is Ineterstingly listed?

@Strauss No. I have that word copyrighted.
