Source etymology 2

Original entry ↗
noun

A portion of a sail rolled and tied down to lessen the area exposed in a high wind. · A reef knot.

verb

To take in part of a sail in order to adapt the size of the sail to the force of the wind. · To pull or yank strongly, especially in relation to horse riding. · To move the floats of a paddle wheel toward its center so that they will not dip so deeply. · To manipulate the lining of a person's pocket in order to steal the contents unnoticed.

Selected source glosses provide context, not a complete modern definition inventory

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”).
