Pro Tip

Avoid double negatives

Do not confuse 'unforeseeable' with 'not foreseeable.' While both are correct, 'unforeseeable' is the more natural and widely used form in formal contexts.

Gold Rule

Use in formal contexts

Reserve 'unforeseeable' for formal writing such as contracts, reports, or academic texts. In casual conversation, simpler terms like 'unexpected' or 'surprising' are more common.

Word Origin
