unintentional
accidental / unplanned / inadvertent
Adjective
This term describes actions or outcomes that occur without a conscious plan or deliberate will. It carries a neutral to slightly apologetic tone, often used to mitigate blame by emphasizing the lack of malice or intent behind a mistake. In legal or formal contexts, it distinguishes between negligence and willful misconduct. While a result may be harmful, the label unintentional specifies that the actor did not desire the specific outcome, separating the action from the intent.
