A noun for a large crow-like bird, appearing in its plural form crebain in The Lord of the Rings (LotR/285). Its singular form craban was given in notes on Words, Phrases and Passages from the Lord of the Rings from the late 1950s or early 1960s, where Tolkien described it as “a bird of the crow-kind” and said it was “not an ancient Sindarin word, and probably a loan from some Mannish tongue of NW or from some non-Eldarin Elvish of the same region” (PE17/37). Jim Allen noted its similarity proto-Germanic *khrabanaz (An Introduction to Elvish, p. 75). The exact species isn’t clear, but it might be a kind of raven.
