A large, dark cloud that can produce thunder and lightning, often associated with storms.
The sky was filled with thunderclouds, signaling an approaching storm.
Thundercloud → It is formed from "thunder" (from Old English *þunor*, meaning a loud noise or rumble) and "cloud" (from Old English *clud*, meaning a mass of rock or hill, later referring to a visible mass of condensed water vapor in the atmosphere). The word "thundercloud" refers to a cloud that produces thunder, typically associated with storms.
Imagine a loud noise ('thunder') coming from a mass of water vapor ('cloud') in the sky — that's why a thundercloud is a cloud that makes thunder.
