Definition: Imperfection is a state of being bad or lacking good qualities, especially in something that is supposed to be perfect or good. In this context, "improper" means something that lacks perfection. For example, if someone says they are not "perfect", it implies that they have some imperfections that need to be worked on and improved upon. So, "imperfection" would refer to something that can be improved upon in a way that makes it better or more desirable in the context of someone's behavior or actions. Similarly, if someone says they are "imperfect", it means that they have some flaws or shortcomings that need to be addressed and corrected. So, "improvement" refers to something that involves changing or improving something so that it is better or more desirable in the eyes of someone else.
