Words that should exist

What are things we don't have words for but would be nice/cool/useful to have sometimes ?



I'd like a word that expresses forgetting what you're searching for while searching for it.

Also for equally loving and hating someone at the same time.

The words "unthirsty" and "ungreen" should also totally exist =P

 

There definitely are words that need to exist but not those you've suggested, in my opinion. Not thirsty will suffice.
'Slipping the mind' is good - you don't need so many words to say that you forgot what you're looking for.
Ambivalent also works nicely for love/hate.
