Interaction is the way two or more people, groups, or things act on, respond to, or influence each other.

- Things affecting each other: “The interaction of heat and moisture caused the paint to peel.”

Common Mistakes to Avoid
- Using “interaction” for one-way action. If only one side acts, use contact or communication instead.
- Mixing up “interface” and “interaction.” An interface is the meeting point. The interaction is what happens there.
- Overusing “synergy.” It can sound like empty business jargon. Collaboration or teamwork is often clearer.
- Using “correspondence” for spoken talk. It refers to written communication.
- Choosing “dealings” for friendly situations. It can sound cold or suspicious. Try relationship or contact.
- Treating all synonyms as identical. Engagement means active involvement, while contact only means being in touch.
- Using “intercourse” as a synonym. Older texts used it to mean social interaction, but today it has a different, sexual meaning. Avoid it.
