Button-shaped is a term used to describe the shape of an object that is similar to a button. However, there are many synonyms that can be used to describe something that is button-shaped. For example, round, circular, disc-shaped, and disk-like are all synonyms that could be used instead of button-shaped. Other options include globular, spherical, orbicular, and ball-shaped. The choice of synonym will depend on the specific object being described and the context in which it is being used. Nonetheless, all of these synonyms describe a shape that is compact, round, and usually a little bit flat.
