rid: [13] The verb rid was borrowed from Old Norse rythja, ancestor of modern Swedish r?dja, Danish rydde, and Norwegian rydja. This in turn went back to a prehistoric Germanic *rudjan. Its past participle rid has been used in the context be rid of, get rid of since the 15th century. Riddance is a 16th-century English coinage.
rid (v.)
c. 1200, "clear (a space); set free, save," from a Scandinavian source akin to Old Norse ryeja (past tense ruddi, past participle ruddr) "to clear (land) of obstructions," from Proto-Germanic *reudijan (cognates: Old High German riuten, German reuten "to clear land," Old Frisian rothia "to clear," Old English -royd "clearing," common in northern place names), from PIE root *reudh- "to clear land." The general sense of "to make (something) free (of something else)" emerged by 1560s. Senses merged somewhat with Northern English, Scottish, and U.S. dialectal redd. To get rid of (something or someone) is from 1660s. Related: Ridden; ridding.
