Which word suggests a significant difference when comparing two items?

The word "contrast" specifically indicates a clear distinction or significant difference between two or more items. It is often used in the context of comparing characteristics, qualities, or features, highlighting the distinctiveness of each element involved. In literary analysis or discussions, identifying the contrast helps to understand themes, characters, or even stylistic choices made by the author.

The other words do not convey the same meaning. "Hint" implies a suggestion or a small indication, lacking the definitive clarity of difference that "contrast" provides. "Impact" refers to the effect or influence something has, which does not inherently suggest a comparison. "Experience" relates to personal encounters or events one goes through and does not imply a comparison at all. Thus, "contrast" is the most appropriate term for indicating significant differences.
