Especially this. I was listening to an episode of Waypoint Radio and Patrick keeps saying ah-toe-mah-ta over and over, then says Automaton flawlessly. IT'S THE SAME WORD. CMON, PATRICK!
It's au-TOM-ah-tah. I too, have no idea why so many otherwise reasonable people are just saying it wrong. This is a real word, and is the plural form of another word that some of those same people pronounce correctly: automaton.
