What is a 7 letter word meaning "sharp-cornered"?

The seven-letter word meaning “sharp-cornered” is angular. As an adjective, angular describes something marked by prominent angles, straight edges, or corners rather than smooth curves.

The word is closely related to angle, which comes from the Latin angulus, meaning “corner.” An angular shape may have clearly defined corners, such as a polygon, a geometric pattern, or a building with sharply meeting surfaces. The term can also describe a person’s physical appearance when the face or body has prominent bones and relatively little rounded fullness.

Angular is sometimes confused with “acute,” but the words are not interchangeable. Acute refers specifically to an angle measuring less than 90 degrees, while angular is a broader description of shape or appearance. In geology, “angular” can also describe sediment particles whose edges and corners remain sharp because they have experienced limited abrasion. The answer contains seven letters: A-N-G-U-L-A-R.
