unintentionally

An unintentional action is one that happens by mistake or without planning. Sometimes people do things they didn't mean to do.

When someone does something unintentionally, it usually means they didn't plan for it to happen. For example, you might spill coffee on your shirt unintentionally while rushing out the door in the morning. Or maybe you hurt someone's feelings unintentionally with a thoughtless comment. In situations like these, people often try to make things right or apologize because an unintentional action can still cause problems.
