Which term describes something that is deserving of blame?

The term that describes something deserving of blame is "reprehensible." This word is specifically used to refer to actions, behaviors, or attitudes that are morally objectionable or deserving of condemnation. It conveys a strong sense of disapproval and highlights that the subject in question is not just blameworthy but also carries a significant ethical or moral implication.

In contrast, "reproachable" also relates to blame, but it does not carry the same weight as "reprehensible." It suggests a level of censure but is often seen as somewhat less severe. "Remarkable" refers to something worthy of attention or extraordinary, completely disconnected from notions of blame. "Regrettable" implies that something is unfortunate or disappointing, which may be worthy of sadness or lament rather than direct blame. Thus, "reprehensible" best encapsulates the idea of deserving blame.
