What does rumbly mean?
Rumbly describes a low, continuous sound or something that produces such a sound. Its clearest use is with a voice: a rumbly voice may sound deep, warm, resonant, or slightly hoarse. It can also characterize vehicles, machinery, thunder, or other sounds that roll or reverberate. When applied to a stomach or belly, it suggests audible digestive movement and is generally lighthearted rather than medical. The word is related to the noun and verb rumble, but it functions specifically as an adjective. Although it occurs in both British and American English, it is most natural in informal speech and descriptive writing. It is particularly effective when a sound seems to come from somewhere deep or distant. In literary contexts, rumbly can add atmosphere, while in casual conversation it often produces a humorous or affectionate effect.

Where does rumbly come from?
Rumbly was formed in English by adding the adjective-forming suffix -y to rumble. Rumble itself developed from the Middle English verb rumblen, denoting a low, continuous sound, and is generally understood as imitative in origin. The derivative rumbly therefore preserves the original association with deep, rolling, resonant noise.
