Definition of rumble

The word "rumble" has its roots in Old English. It comes from the word "rumbl", which is derived from the Proto-Germanic word "*rumiz", which means "to make a low sound". This Proto-Germanic word is also the source of the Modern German word "rummen", meaning "to rumble". The word "rumble" initially meant "to make a low, rumbling sound" and was used to describe the sound of thunder, a rolling drum, or the noise of a moving crowd. Over time, the meaning of the word expanded to include any low-pitched, prolonged noise, such as the sound of an engine or a stomach growling. In the 16th century, the word "rumble" was also used to describe the act of producing such a sound, and it has since been used in a variety of contexts, including literature, music, and even idiomatic expressions like "a rumble in the jungle" to describe a legendary fight.
