An adjective "rotund" describes someone or something that's round and full-bodied.
When people talk about food, they often use the word "rotund" to describe dishes like bread rolls or donuts – things that are plump and rounded. This means you can think of the word as describing a shape more than anything else. But it can also be used to talk about people who have a bit of extra weight or a big, round face. Some people use "rotund" in a slightly different way too, talking about buildings or monuments that are grand and imposing – like a rotund church with a large dome.
Having a round or spherical shape; circular; orbicular.
