Out of deference to Babylon 5’s Delenn, I must note: crotchety

Delenn: Ivanova sent me to find you. She says you haven’t been sleeping, that you have barely been eating. She says that you have been, in her words, ‘carrying on cranky’. I looked up the word ‘cranky’, it said ‘grouchy’. I looked up the word ‘grouchy’, it said ‘crotchety’. No wonder you have such an eccentric culture. None of your words have their own meanings – you have to look up one word to understand another. It never ends.
Sheridan isn’t listening to her. He is focused on the galactic map.

Sheridan: Something here doesn’t make sense.
Delenn: That is what I thought when I came across ‘crotchety’. This cannot be a real word, I said.
