Firstly, Hello. I enjoy much of this forum, so I have joined.
Secondly, is there a term for a word where a negative exists but the opposite doesn't, or at least is not in common use.
For example: "unkempt" I've never heard anyone described as "kempt" even though it may well exist.
Any other examples welcome. I have a list somewhere on my PC.
Best regards to all from Yorkshire
