More bulbous can also be described as rounder, fuller, plumper or bloated. The word bulbous is often used to describe the shape of something that is rounded and swollen, such as a potato or a nose. Expanding the vocabulary to include different synonyms can add a descriptive layer to the object being described. For example, instead of saying a potato is more bulbous, it could be stated as a plump potato or a fuller potato. This way, the reader or listener can gain a clearer understanding of the object through a variety of descriptive words.
