When we use the phrase "eating one's word," it's usually because someone has made a statement or a prediction that turns out to be incorrect, and they have to backtrack or retract what they said. There are several other phrases that can describe this situation, including "crow is on the menu," "humble pie," "take back one's words," and "put one's foot in one's mouth." All of these phrases refer to the discomfort and embarrassment that can come from having to admit that we were wrong or that we spoke too soon. Ultimately, the lesson is to choose our words carefully and be willing to apologize when necessary.
