What does corner mean?
A corner is the point at which two lines, edges, or surfaces meet — the junction where walls converge, where streets intersect, or where a page folds. The word extends naturally to any sheltered or tucked-away space, as when a shy guest retreats to a quiet corner of a room. Beyond the physical, corner carries rich figurative weight: to be 'in a tight corner' is to face trouble with few options, while to 'turn the corner' signals passing through a crisis toward recovery. In commerce, cornering a market means gaining dominant control over supply. It also functions as a verb meaning to trap someone so they cannot escape. Derived from Latin cornu, meaning horn, it shares ancestry with words like unicorn and cornea, since both corners and horns are pointed projections. Versatile, concrete, and metaphorically productive, corner is among the most useful spatial terms in English.
A point or area where two lines, sides, or surfaces meet; a secluded spot within a larger space; figuratively, a difficult situation with limited options or control over a market.
"He parked the car on the corner of Fifth and Main."
Figurative uses include 'in a tight corner' (facing difficulty) and 'corner the market' (dominate a market).
To trap a person or animal in a confined position with no easy escape, or to gain exclusive control over a market or commodity.
"Reporters finally cornered the senator outside the hearing room."
Standard plural, used freely for both literal points where surfaces meet and figurative spaces or situations.
"Wipe down all the corners of the room before painting."
"Corner" and "coroner" look like cousins, but only one comes from Latin cornu — a horn — which is why your eye's cornea and a unicorn are literally family.

Etymology of corner
Corner entered Middle English, likely via Anglo-Norman, from Old French cornier, derived from Latin cornu, meaning horn or the projecting point of one. The underlying sense is of a pointed projection, matching cognates such as cornea, cornet, and unicorn that all descend from the same Latin root. The word has been in continuous use for its core geometric and spatial senses since medieval times.
How corner is actually used
Corner is neutral in register and common in both everyday speech and writing. Figurative uses such as 'turn the corner' (pass a critical point toward improvement) and 'be in a tight corner' (face difficulty) are well established. As a verb, it is usually used of trapping a person or dominating a market.
