Dither is a verb that means to behave indecisively.

Coming from Middle English, our word of the day once meant to ‘tremble’ or ‘shake.’ Today, we use the word to describe a different kind of going back and forth.

It was funny to watch my dad dither on the team he wanted to cheer for. He went back and forth between the Cubs — because he’d always been a Cubs fan — and the Twins — because his nephew was now their starting catcher.
