What term is used for something that is lacking wit or imagination?

The term "pedestrian" refers to something that is dull, unremarkable, or lacking in imagination and creativity. In this context, it describes work or ideas that are ordinary and uninspired, as opposed to being original or inventive. The word is often used to characterize written work, art, or concepts that do not stand out due to a lack of distinctive qualities or flair. Thus, it appropriately conveys the sense of deficiency in wit or imagination that the question highlights.

The other terms describe positive attributes rather than deficiencies. "Creative" implies imaginative and inventive ability, "innovative" suggests new and effective ideas or methods, and "exceptional" indicates something that is outstanding or extraordinary. These words do not align with the concept of lacking wit or imagination, reinforcing why "pedestrian" is the appropriate choice.
