Etymology: "Collied" is the past form of "colly," a verb meaning to blacken or smudge with coal dust or smoke. The verb has two Middle English ancestors. One is a form of "coal" with the adjectival ending "-y," from Old English "coliġ," which shares its root with the modern word for the fuel. The other is a separate verb, from Old English "colgian," which surfaced in Middle English as "colien" and its variants "colwen" and "colwinge," all meaning to make dark or sooty. The two strands merged over time, so "colly" now stands in a doublet relationship with "coaly," which descends from the same Middle English adjective and kept the adjectival sense. The verb carried the sense of soiling outward, so that a surface could be "collied" by smoke or carbon even without being coated in coal itself.
