What Does Leaps and Bounds Mean?

By Leaps and Bounds Meaning

Definition: Moving forward in surprisingly large and rapid steps.

 This idiom means that progress is made quickly in big strides, rather than slowly and steadily. It is often said with a hint of surprise, as if no one expected the progress to go so quickly or so far.

The phrase implies that perhaps the normal steps of progression were sidestepped, and the growth instead leaped over certain stages and moved ahead more quickly than normal.

They have been paired since the early 1700s, though early sources are hard to come by. We can see variations of the phrase in the 1837 Western Courier from Ravenna, Ohio:

  • The noble animal gave a leap, one bound, and as the blood gushed in torrents from his breast, staggered and fell.

We can see other 19th-century examples from an 1838 copy of The Native American:

  • We do not turn over the musty manuscript of the hoary past— but we leap and bound along with the swift current, swifter than ever…
  • …he looked at you, and your very soul bounded and leaped beneath the swimming glance of the philosopher.
