Unkindness
noun /ˌʌnˈkaɪndnəs/ — A group of ravens — and a beautifully dark name for it.
Definition
The collective noun for a group of ravens — chosen with poetic precision, as ravens have been associated with ill omen, death, and the uncanny since at least the Norse tradition.
Beyond the definition
The person who named an unkindness of ravens understood something true about language: that the best collective nouns are not merely descriptive but interpretive. They apply a moral or emotional quality to a group, telling you how to feel about it.
Origin & history
English collective noun tradition, possibly medieval. Ravens were associated with battlefields, the Tower of London, and death omens — the name reflects all of this.
