inconceivable

word

Impossible to imagine or believe; so unlikely or unbelievable that it cannot be thought possible.

Usage & Nuances

Used in formal and informal contexts to express extreme shock or disbelief. Often used with strong events or ideas. Common after words like 'almost', 'seem', or as an exclamation. Do not confuse with 'impossible'—'inconceivable' emphasizes imagination or belief, not just feasibility.
