Words, No. 9

Malfeasance is a word I can't comfortably define.

Run is a highly convincing verb, especially when phrased as an imperative.

Urund is not a word.

Gerund looks like it isn't a word either, but it really is.

Brobdingnagian seems like a made-up word because it is.

Ersatz is something that bridges hopefully aren't.
