What term would you use to describe something that is ordinary in nature?

The term "mundane" is used to describe something that is ordinary or lacking in excitement or interest. It refers to the day-to-day aspects of life that are common and unremarkable. In contrast, the other choices represent concepts that are either distinctive or exceptional. For example, "unique" suggests something that is one-of-a-kind or unlike anything else, "standard" implies a level of quality or form that is established as typical but does not necessarily convey ordinariness in the same way, and "remarkable" highlights something that is worthy of attention due to its significance or unusual characteristics. Therefore, "mundane" is the most fitting choice to describe something that is ordinary in nature.
