verb (past participle shorn /SHôrn/ or sheared)
- a strain in the structure of a substance produced by pressure, when its layers are laterally shifted in relation to each other. See also wind shear.
Old English sceran (originally in the sense 'cut through with a weapon'), of Germanic origin; related to Dutch and German scheren, from a base meaning 'divide, shear, shave'
The two verbs shear and sheer are sometimes confused: see sheer2 (usage).
The different forms of this verb are: (shears, shearing, sheared; the past participle is shorn or sheared).
Do not confuse shear with sheer. Shear means 'cut the wool off a sheep'. As a verb, sheer means 'change course quickly' (the road sheered off into the darkness); sheer is also an adjective chiefly meaning 'nothing but; absolute' (the sheer joy of skydiving).
