The word "rumble" refers to a low, continuous sound that often resembles a distant roar or growl. This sound can be created by various sources, such as thunder, rolling machinery, or even the stomach when hungry. Additionally, "rumble" can also mean to engage in a physical fight or brawl, especially among young people.
The word "rumble" originates from the late Middle English term "rumblen," which means to make a low, heavy sound. Its roots can be traced back further to the Old French word "romble," meaning a noise or rumbling.
