Which word signifies a negative change in emotion or feeling?

The word "poignant" signifies a negative change in emotion or feeling because it is often used to describe something that evokes a strong sense of sadness, regret, or deep emotion. Although poignant moments can be powerful and impactful, they frequently contain elements of sorrow or distress. When people describe a memory or an experience as poignant, it suggests that it brings forth difficult emotions, highlighting the aspect of emotional change.

In contrast, "scarcity" refers to a lack or shortage of something and does not directly relate to emotional states. "Scold" pertains to reprimanding someone, which can have a negative connotation but focuses on an action rather than a change in feeling. "Debris" refers to scattered pieces of waste or remains, lacking any emotional relevance. Thus, "poignant" stands out as the option that directly signifies an impactful shift in emotion, particularly towards the negative.
