Emily Dickinson Lexicon

CLOUD, n. [I have not found this word in any other language. The sense is obvious – a collection. Its elements are those of clod, and L. claudo.]

1. A collection of visible vapor, or watery particles, suspended in the atmosphere, at some altitude. A like collection of vapors near the earth is usually called fog. – Locke. I do set my bow in the cloud. – Gen. ix. Behold a white cloud. – Rev. xiv.
2. A state of obscurity or darkness. – Waller. Addison.
3. A collection of smoke, or a dense collection of dust, rising or floating in the air; as, a cloud of dust. A cloud of incense. – Ezek. viii.
4. The dark or varied colors, in veins or spots, on stones or other bodies, are called clouds.
