“shear” vs. “sheer”
Use "shear" for the verb meaning to cut or clip (or the related noun for cutting force); use "sheer" for the adjective meaning pure, steep, or transparent.
shear
"Shear" is a verb meaning to cut or clip, especially wool from a sheep ("shear the flock every spring"), or more broadly to cut off cleanly with a sharp instrument or force ("the wind sheared the branch off"). It comes from Old English "sceran," related to "shears," the large scissor-like tool used for cutting wool, hedges, or metal, and also survives in engineering as "shear force," describing a mechanical stress that causes materials to slide against each other.
sheer
"Sheer" is an adjective with several related senses: completely pure or total ("sheer luck," "sheer terror"), very steep or vertical ("a sheer cliff face"), or, describing fabric, so thin as to be transparent ("sheer curtains," "sheer stockings"). It comes from Middle English "schere," related to Old Norse "skirr," meaning bright or clear, a root that explains the fabric sense (clear enough to see through) and extends metaphorically to the sense of "pure" or "utter."
The real distinction
"Shear" is a verb (or the noun for the cutting tool) describing an act of cutting or a force that causes cutting-like sliding, while "sheer" is an adjective describing purity, steepness, or transparency, and despite identical pronunciation the two rarely overlap in real sentences because their grammatical roles differ so completely. Confusion sometimes arises in descriptions of cliffs or drops, where a steep rock face (correctly "sheer cliff," the adjective) might be mentally associated with something being "cut off" abruptly, tempting a writer toward the incorrect "shear cliff" — but the adjective describing steepness is always "sheer." A reliable check: if the word needs an object being cut, clipped, or sliced, it's the verb "shear" ("shear the sheep," "the storm sheared the roof off"); if the word describes an intensity, a steep angle, or a transparent fabric, it's the adjective "sheer" ("sheer joy," "sheer drop," "sheer fabric"). Engineering and physics contexts specifically favor "shear" as a technical noun ("shear stress," "shear strength"), a specialized usage worth knowing if you write about materials science or construction. It's also useful to know that "shear" survives in a number of specialized compound nouns beyond sheep farming, including "wind shear," a sudden change in wind speed or direction that pilots must account for during takeoff and landing, and "shear pin," a mechanical safety component designed to break under excess force to protect more expensive machinery — both technical uses reinforcing the core idea of a sudden, forceful separation.

Memory trick
Picture a pair of shears (scissors) cutting through wool — "shear" is the action of the blades. "Sheer" has an extra flavor of intensity, so think of "sheer" curtains as so thin they're almost "clear" — both words share that long "ear" sound, but only "shear" involves an actual cutting tool.
