unintentional

Done without meaning

Unintentional describes something done without meaning to do it—an accident rather than a deliberate act.

An unintentional insult wasn't meant to offend.

An unintentional omission was an oversight, not a cover-up.

The word often appears in legal and formal contexts to distinguish careless acts from purposeful ones: The shooting was ruled unintentional.
