Which word describes someone who is "graceless"?

The term "graceless" refers to a lack of grace, elegance, or smoothness in movement or behavior. The word "ungainly" perfectly captures this concept, as it describes someone who is awkward, clumsy, or lacking in physical agility. It suggests a certain heaviness or inelegance in motion, which aligns well with the idea of being graceless.

In contrast, the other options describe qualities that are opposite or not consistent with the idea of being graceless. "Nimble" conveys quickness and lightness of movement, "agile" implies a strong ability to move quickly and gracefully, and "supple" refers to flexibility and ease of movement. Therefore, these words do not fit the description of someone who is graceless.
