GIMP, or GYMP. (i) (Of somewhat doubtful origin, but probably a nasal form of the Fr. guipure, from guiper, to cover or " whip " a cord over with silk), a stiff trimming made of silk or cotton woven around a firm cord, often further ornamented by a metal cord running through it. It is also sometimes covered with bugles, beads or other glistening ornaments. The trimming employed by upholsterers to edge curtains, draperies, the seats of chairs, etc., is also called gimp; and in lace work it is the firmer or coarser thread which outlines the pattern and strengthens the material. (2) A shortened form of gimple (the O.E. wimple), the kerchief worn by a nun around her throat, sometimes also applied to a nun's stomacher.
