What does rotund mean?
Rotund is a formal adjective describing something that is rounded, full, or plump in shape. It can refer to a person's body or figure, as well as to objects and forms that have a substantial, bulging outline. The word often carries a slightly humorous or literary tone: calling someone rotund may be more playful or euphemistic than saying they are plump, though it can still be considered an insensitive description when used thoughtlessly. In older and more formal writing, rotund also functions as a noun for a rotund person. Its distinctive history comes from Latin rotundus, meaning “round,” which is related to rota, “wheel.” That same root appears in words such as rotate, rotation, and rotunda. Rotund is therefore useful when precision about roundedness matters, especially in literary, descriptive, or deliberately elegant contexts.
