Finance

"The company faced unforeseen costs due to the recent market fluctuations."

News

From Middle English 'unforseene,' meaning 'not foreseen.' The prefix 'un-' negates the past participle of 'foresee,' meaning 'to see or know beforehand.'

The word 'unforeseen' has been used in English since the early 17th century, evolving from legal and philosophical contexts to broader application in general discourse.

Memory tip

Think of 'un-' (not) and 'foreseen' (seen ahead). Something unforeseen is something you didn't see coming.
