Prodigiousness, which refers to exceptional, remarkable, or outstanding qualities, can easily be expressed with its opposite, which is a lack of significant qualities or the presence of mediocrity. Some antonyms for prodigiousness are: unremarkable, ordinary, average, mediocre, commonplace, and run-of-the-mill. These antonyms are used to describe things or people that lack special characteristics or standout features, making them less impressive than their counterparts. In contrast to prodigiousness, the absence of exceptional qualities does not necessarily mean that something or someone is inferior or incapable. However, it denotes a lack of something that sets it apart from the rest.
