"Cucumber-shaped" is often used to describe an object that has a slender, elongated body with a rounded end. However, there are several synonyms which can be used to describe this shape. One such synonym is "cylindrical", which denotes a shape that is long and round, like a cylinder. "Tubular" is also a good synonym for cucumber-shaped, as it describes an object that is long and hollow with a round cross-section. Additionally, "spindle-shaped" can be used to describe a shape that gradually tapers towards the ends, resembling a spindle. Lastly, "elliptical" can be used to describe a shape that is oval or egg-shaped, which can also be similar to the shape of a cucumber.
