The antonyms for the word "more characterful" refer to a lack of character, personality, individuality and uniqueness. Words such as bland, ordinary, conventional, uninspired and unremarkable come to mind. These words describe a space or a person that is lacking in originality, creativity and distinctiveness. They also imply a sense of sameness and predictability, which can be stifling and uninteresting. In contrast, the opposite of characterless, that is, having more character, suggests a quality of being unique, vibrant and full of personality. This could be applied to anything from a home interior to a personal style or a particular community.
