C'est mort !

The expression "C'est mort !" literally translates to "It's dead!" in English. Its origin can be traced to the metaphorical use of the word "mort" (dead) to signify the end, failure, or impossibility of something. This kind of metaphorical usage is common across many languages, where death is associated with finality and the cessation of existence or possibility. While a precise historical document marking the first use of "C'est mort !" in this idiomatic sense is difficult to pinpoint, the development of such an expression likely evolved organically within spoken French, drawing on the existing connotations of 'death'. The word 'mort' itself comes from the Latin 'mors' (death), and its derivatives and related concepts have long been used in various idiomatic expressions in French to denote an end or absence of life or hope. Over time, phrases like "c'est mort" or "être mort" when applied to a situation or an object, moved beyond literal death to signify that something is defunct, impossible, or has no chance of succeeding. It conveys a strong sense of hopelessness or definitive failure regarding a particular outcome or event. It is a colloquial and somewhat informal expression, commonly used in everyday conversation to quickly communicate that a plan or possibility is no longer viable.
