Example: John has a broken leg with a cast on it. He cannot put the broken leg flat on the floor. To get from his bed to his desk, would we say he walked? Wouldn’t it be more precise to say that he hopped? Or perhaps hobbled?
Example: Robert needs to be on the 8:00 a.m. bus to Manhattan. It is now 7:55. The bus stop is three blocks away. Is Robert going to walk to the bus stop? Wouldn’t it be more precise to say that he ran or dashed to the bus stop?
Example: You discover a previously undiscovered tunnel in the side of a mountain. You want to give the reader the idea that the tunnel is not very tall. If you say that you walked through the entrance, then the tunnel’s ceiling is higher than your height. If you say you crawled, the reader automatically knows that the ceiling height was too low for you to stand up straight.
