thunder
The sound which follows an explosion of electricity or lightning; the report of a discharge of electrical fluid, that is, of its passage from one cloud to another, or from a cloud to the earth, or from the earth to a cloud. When this explosion is near to a person, the thunder is a rattling or clattering sound, and when distant, the sound is heavy and rumbling. The fact is in some degree the same with the report of a cannon. This sharpness or acuteness of the sound when near, and the rumbling murmur when distant, are the principal distinctions in thunder. There were thunders and lightnings. Exodus 19:16.
