'Shear' is to cut or clip (especially wool); 'sheer' means pure or utter, or describes fabric that is very thin and transparent.
"Shear" is to cut with blades or to clip wool from a sheep. "Shear the sheep" = remove the fleece. In physics: a shearing force acts on two surfaces in opposite directions, causing deformation.
The farmer shears his sheep every spring before the hot season.
The bolt sheared off under the excessive pressure.
Use garden shears to trim the hedge into a neat shape.
"Sheer" as an adjective means utter and complete ("sheer luck" = nothing but luck), very thin and transparent ("sheer fabric"), or nearly vertical ("sheer drop" = a near-vertical fall).
It was sheer determination that got her through the marathon.
The cliff dropped in a sheer vertical fall to the ocean below.
She wore a sheer blouse over a white camisole.
Common mistake
Trick to remember it
Quick rule
Is it the verb to cut or clip? "Shear." Is it the adjective for utter, transparent, or nearly vertical? "Sheer."
Did you know?
"Shear forces" in engineering are forces acting parallel to a surface in opposite directions, like the two blades of scissors. They are fundamental in the design of bridges, aircraft, and skyscrapers: a well-designed bridge must resist not only vertical weight but also the horizontal shear forces caused by wind or earthquakes. The San Andreas Fault in California is a natural example of shear on a massive scale: two tectonic plates sliding in opposite directions, accumulating enormous tension over centuries and releasing it as an earthquake.
Exercise 1 · Pick the right one
The farmer _____ ed the sheep in spring before the warm weather arrived.
Exercise 2 · Pick the right one
It was _____ luck that she found the wallet — she just happened to look down.
Exercise 3 · Form the word
One means to receive or agree to something, the other means to exclude or not include.
'Advice' is the guidance you receive (noun); 'advise' is the act of giving that guidance (verb).
'Affect' is the verb meaning to influence something; 'effect' is the noun meaning result or consequence.
'Aisle' is the walkway between rows of seats or shelves; 'isle' is a small island.
