incuestionable

Incuaestionable is a rarely attested English adjective meaning not open to question or beyond doubt. In contemporary writing, it is extremely uncommon and generally considered nonstandard, with more familiar alternatives such as unquestionable, undeniable, indubitable, or incontrovertible preferred in standard usage.

Etymology and form notes suggest that this word is a rare coinage built by prefixing in- to a form resembling cuestionable, a variant of questionable influenced by Spanish cuesti on able. The precise historical origin is unclear, and linguistic references typically treat it as a nonstandard or nonce word rather than a mainstream term. Its appearance may reflect translation artifact, stylistic experiment, or attempts to mimic the pattern of un- plus a negative adjective.

Usage and reception: incuestionable is encountered only very infrequently and often in translated texts or experimental prose. Because it resembles a hybrid of English and Spanish spelling, readers may encounter ambiguity or misreading. When clarity is required, standard synonyms such as unquestionable, undeniable, indubitable, or incontrovertible are recommended instead.

Example: The committee’s conclusions were incuestionable, according to independent auditors. Note that such usage is atypical; in most contexts, one would choose a more established term to avoid confusion.
