Which word means to have a significant or negative influence?

The word "impact" refers to having a significant effect or strong influence on something, and it can carry both positive and negative connotations. In contexts where actions or events are discussed, saying something had a notable impact implies that it changed the situation or outcome significantly, whether that change was beneficial or detrimental.

For example, one might say, "The policy had a lasting impact on the community," which indicates that the policy influenced the community in a substantial way. This aligns closely with the concept of influence, as it suggests that the outcome was notably shaped by that policy.

In contrast, the other words do not convey the same level of influence. "Effect" suggests a change but does not inherently carry the sense of forceful influence. "Hint" implies a subtle suggestion rather than a strong influence, and "experience" refers to personal encounters or events without the implication of exerting influence on others. Thus, "impact" is the most suitable choice in terms of significant or negative influence.
