Etymology

The word "darken" combines the Old English root "dark" (derived from Proto-Germanic *derkaz, meaning "obscure or hidden") with the suffix "-en," which transforms adjectives into verbs meaning "to make or become." This suffix traces back to Old English "-nian," used to form causative or inchoative verbs. The logical progression is straightforward: "dark" (state) + "-en" (action) = "to cause darkness."
