### Etymology 2

From Middle English reef, from Old Norse rif, Middle Dutch rif, rēve, and/or Middle Low German ref. Possibly a figurative use of the word for “rib” in etymology 1 above, in which case all forms must, again, be borrowings from Old Norse. Alternatively it may be a different word related to Old English rift (“curtain, veil”), ārāfian (“to uncoil, wind off”).

** 1994, Herb Wharton, Cattle Camp: Murrie Drovers and Their Stories, published 2010, page 73:Alf told me that one young white stockman, eager to impress the girls, went outside and mounted his horse, then began showing off his prowess, racing past the pub, wheeling and reefing his horse up and down the street, yackeyeing and whooping, flogging his horse with a battered old hat and always turning towards the pub to see if the girls were watching these feats of horsemanship.
