How It's Used

General conversation

"He unintentionally offended her with his blunt comment."

Legal context

"The damage was caused unintentionally, which lessened the severity of the penalty."

From 'un-' (not) + 'intentionally' (with intent). 'Intentionally' comes from 'intention,' which is from the Latin 'intendere' (to aim at).

The use of 'unintentionally' has been consistent since its emergence in the 17th century, reflecting increasing emphasis on the motivations behind actions.

Memory tip

Think of 'intention' – the opposite is 'unintentionally'. So it means something happened without you meaning for it to.
