wildly
In a very uncontrolled, excited, or extreme way.
Wildly means in an uncontrolled, extreme, or intense way. When something happens wildly, it goes beyond normal limits or ordinary behavior.
If your heart beats wildly before giving a speech, it's pounding much harder and faster than usual. When a crowd cheers wildly after an incredible play, they're shouting, jumping, and celebrating with total enthusiasm. A dog might wag its tail wildly when its owner comes home, swishing it back and forth so vigorously that its whole body wiggles.
The word often describes things that are out of control or difficult to predict. Flames might spread wildly through dry grass. A rumor could spread wildly through school, growing more exaggerated with each retelling. Prices might swing wildly up and down.
Wildly can also mean extremely or remarkably, especially when something exceeds expectations. A movie might be wildly successful, meaning it did far better than anyone predicted. A guess could be wildly inaccurate, meaning completely off the mark. When your friend makes a wildly optimistic prediction about winning every game this season, they're being unrealistically hopeful.
