Sense: adjective/1
U-shaped specifically describes something that has the form of the letter U — a flat bottom with two straight sides rising upward. Horseshoe-shaped is similar but usually implies a narrower, more rounded curve at the bottom (like a real horseshoe). Curved is a much broader term covering any line that is not straight; a U-shaped object is always curved, but a curved object is not necessarily U-shaped. Bent means forced out of a straight line, often at an angle, but may lack the smooth symmetrical arc of a U-shape. For example, a road that bends sharply to avoid a rock is bent; a road that loops around a valley in a smooth U form is U-shaped.

Etymology
U-shaped is a compound word formed from the letter name 'U' (referring to the shape of the capital letter) and the adjective 'shaped', from Old English 'gesceapen' (past participle of 'scieppan' meaning to create or form). The word emerged in the early 1800s as English speakers began describing objects, especially furniture and geographical features, by their resemblance to the capital letter U.
