When describing a structure or object that has a rounded, curved, or bulging top, the term "more domed" might be the first to come to mind. However, there are several synonyms that can be used to give a more varied and descriptive account. For example, the terms "arched", "curved", "vaulted", "rounded", "bulging", "humped", "swollen", and "dome-shaped" can all be used to convey this characteristic. These words can add depth and nuance to your writing, making your descriptions more vivid and engaging. So whether you are describing a towering cathedral or a humble mud hut, there are plenty of synonyms to help you capture its unique shape and form.
