Sure, but I have never heard anyone use this either. This is not common in discourse.

I also find the wiki description and your comment somewhat ambiguous. Even in this case it's hard to descern between absence of want or a negative want.

Edit: due to either my own personal misunderstanding or maybe cultural niche, "reject" is also ambiguous because it could mean an absence of want and not necessarily a negative want. However I just learned that in semiotics "reject" does mean distinctly a negative.

So yep, "diswant" is exactly what I've seen lacking.

Now the question is why don't people use it more?

I'll try.

Thanks for sharing.
