"Words pack power and these definitions are laden with values, often wildly idiosyncratic ones. Here's an example, namely the ways I think about the word "competition": (a) "competition"--your lab team races the Cambridge group to a discovery (exhilarating but embarrassing to admit to); (b) "competition"--playing pickup soccer (fine, as long as the best player shifts sides if the score becomes lopsided); (c) "competition"--your child's teacher announces a prize for the best outlining-your-fingers Thanksgiving turkey drawing (silly and perhaps a red flag--if it keeps happening, maybe complain to the principal); (d) "competition"--whose deity is more worth killing for? (try to avoid)."
