What term describes a physical or mental condition that makes it difficult for you to do things?

The term that best describes a physical or mental condition that makes it difficult for an individual to perform certain activities is "disability." This term encompasses a wide range of impairments that affect major life activities, and it recognizes the limitations that arise from these conditions. A disability can be physical, such as a mobility issue, or mental, involving cognitive challenges that affect daily functioning.

"Impairment" refers more specifically to a loss of function or ability in a particular area, which could be a component of a disability but does not encompass the broader impact on daily life. "Condition" is a more general term that could refer to any state of health, but it lacks the specificity needed to convey the challenges associated with performing everyday activities. Lastly, "ailment" usually describes an illness or disorder but does not necessarily imply a long-term limitation, making it less precise in this context. The choice of "disability" highlights the real-world implications of such conditions on a person's ability to engage in routine tasks.
