not a chance
Meaning
There is absolutely no possibility; definitely not.
Origin
From the literal idea of having no opportunity (“no chance”), intensified as a firm refusal/denial in conversational English, especially from the mid–late 20th century onward.
Notes
A strong, informal denial/refusal. Can sound blunt or dismissive; soften in polite contexts (e.g., “I’m afraid that won’t be possible.”).

Grammar & Usage Notes
Usually used as a standalone reply (“Not a chance.”) or after/within a clause (“There’s not a chance…” / “Not a chance I’m doing that.”). Often takes emphatic stress; can be expanded to “not a chance in hell” (stronger, cruder).
