For whatever reason, I can’t (or couldn’t) seem to remember what they mean:
anodyne (and I’ll probably end up looking this one up again.)
cromulent (but, hey, it’s a made-up word from the Simpsons.)
sanguine (no really. I think the root in ‘blood’ makes the optimistic meaning seem weird – so I forget it.)
And, of course, a dozen other words I can’t remember at the moment.
