QEDssä

QEDssä is a Finnish slang term that broadly translates to "in QED" or "as expected from QED." It is often used humorously or sarcastically to comment on a situation that has unfolded in a predictable, perhaps even cliché, manner, especially when that situation is perceived as negative or problematic. The term originates from the Latin phrase "quod erat demonstrandum" (which was to be demonstrated), famously used in mathematics and logic to signify the conclusion of a proof.

The application of "QEDssä" in everyday conversation leverages this formal, conclusive implication to highlight the inevitability or obviousness of an outcome. For instance, if a public service announcement is made about a problem that has been widely discussed and understood for a long time, someone might remark "QEDssä" to imply that the announcement was entirely predictable and unsurprising, given the circumstances. It can also be used to point out a self-fulfilling prophecy or a situation where the result was apparent from the outset. The term's usage is informal and carries a sense of wry observation or resignation.
