clampn.¹

Brit.

/klamp/, U.S.

/klæmp/

Etymology: Known since 15th (or 14th) cent. Also in Dutch (since 16th cent.) klampe , now klamp , ‘clamp, cleat’, Low German and modern German klamp , klampe , in High German dialect klampfe ; on West Germanic type *klampa weak feminine, and *klampo weak masculine, belonging to a stem *klamp- , supposed to be a byform of *klamb- , klamm- : see clam n.¹, with which this word is to a certain extent synonymous. From the same stem, Middle High German had klampfer, and modern High German dialect klampfer, klamper (Bavarian), in sense of modern German klammer a clamp. Whether the English word was adopted < Low German or Dutch, or was a native derivative which happens not to be known in Old English or Middle English up to the 14th cent., is uncertain.

a. A brace, clasp, or band, usually of iron or other rigid material, used for giving strength and support to flexible or movable objects, or for fastening two or more things securely together. In many technical senses:e.g. A bar of iron for binding together stones in a building, also a metal clasp or rivet for broken china-ware, etc.; a piece of wood attached to or inserted into another to strengthen it and prevent warping.

释义	clampn.¹ Brit. /klamp/, U.S. /klæmp/ Etymology: Known since 15th (or 14th) cent. Also in Dutch (since 16th cent.) klampe , now klamp , ‘clamp, cleat’, Low German and modern German klamp , klampe , in High German dialect klampfe ; on West Germanic type klampa weak feminine, and klampo weak masculine, belonging to a stem klamp- , supposed to be a byform of klamb- , klamm- : see clam n.¹, with which this word is to a certain extent synonymous. From the same stem, Middle High German had klampfer, and modern High German dialect klampfer, klamper (Bavarian), in sense of modern German klammer a clamp. Whether the English word was adopted < Low German or Dutch, or was a native derivative which happens not to be known in Old English or Middle English up to the 14th cent., is uncertain. 1. a. A brace, clasp, or band, usually of iron or other rigid material, used for giving strength and support to flexible or movable objects, or for fastening two or more things securely together. In many technical senses:e.g. A bar of iron for binding together stones in a building, also a metal clasp or rivet for broken china-ware, etc.; a piece of wood attached to or inserted into another to strengthen it and prevent warping.
