What does cretinous mean?
"Cretinous" is an adjective meaning extremely stupid, senseless, or idiotic. It is the adjectival form of "cretin," a word that once referred — with genuine compassion — to people in the Alpine regions of France and Switzerland who suffered from congenital iodine deficiency, a condition that caused stunted growth and intellectual disability. Over time, however, "cretin" shed its clinical and charitable origins and became a general term of abuse for a fool, with "cretinous" following suit. Today the word is used chiefly to condemn actions, decisions, ideas, or behavior rather than to describe people directly: one might call a policy cretinous, a plot cretinous, or a mistake utterly cretinous. It carries a strong, contemptuous charge and sits comfortably in informal and semi-formal British usage, though it is understood in American English as well. Given its history as a label for real cognitive disability, careful writers increasingly avoid it, preferring alternatives such as "foolish" or "ill-judged." Its etymology — from a dialectal word for "Christian" — remains one of the more surprising stories in modern English invective.
adjectiveUtterly stupid or senseless; characteristic of a cretin. Also used to describe something so foolish or badly done as to seem idiotic.
- Extremely stupid or senseless; showing a complete lack of intelligence or judgment (often of actions, policies, or behavior).
"The decision to pave over the wetlands was simply cretinous."
"It would be positively cretinous to sign the contract without reading it first."
"The reviewer dismissed the film's plot as cretinous and its dialogue as worse."
"Cretinous" traces back through French to a Swiss Alpine dialect word meaning "Christian" — originally a compassionate euphemism for people with congenital intellectual disability caused by iodine deficiency, before it hardened into an insult.

Etymology of cretinous
"Cretinous" derives from "cretin," which entered English in the late 18th century from French. The French word itself comes from a dialect of the Franco-Provençal-speaking Alps, where "crestin" meant "Christian" and was used humanely to refer to people affected by congenital iodine deficiency — a reminder that they had souls like any other Christian. As the medical understanding of the condition developed, "cretin" drifted into general use as a synonym for a fool, and "cretinous" emerged as its adjective. Related forms include "cretinism," the clinical name for the underlying condition.
How cretinous is actually used
Informal to mildly formal register; strongly pejorative. Because "cretin" originated as a medical term for congenital hypothyroidism (myxoedematous cretinism), some style guides and disability advocates discourage its use as an insult. More common in British English than American English.
Easily confused with cretinous
