What is the term for something that is considered forgetting or neglect?

The term that aligns with the idea of forgetting or neglect is "slur." In this context, "slur" refers to a lapse or oversight, often implying a casual disregard or failure to give proper attention to something. This definition encompasses both elements of forgetting and neglect, as it suggests a devaluation or oversight of something that merits attention.

In contrast, the other options do not convey this meaning. "Scorch" typically relates to burning or damaging something through heat, which does not connect to the concepts of forgetting or neglect. "Servile" describes a submissive or excessively obedient attitude, which again does not align with the notion of neglecting something. Lastly, "squalid" refers to something that is extremely dirty or unpleasant, often due to poverty or neglect, but it more specifically describes a condition or state rather than the act of neglecting itself. Therefore, "slur" is the most fitting term for the idea presented in the question.
