Danish word of the day: sindssygt
We have an insane word of the day for you to learn today.
The Danish word sindssygt is a widely used adverb in spoken, colloquial Danish.
The literal meaning of sindssygt is “mind sick” ( sind = mind, syg = sick), or more accurately translated to “insane”. Sindssygt is the adverbial/neuter form of the adjective sindssyg.
More colloquially, sindssygt is used as an intensifier meaning "insanely," "crazy," or "wildly". It amplifies adjectives both positively and negatively.
The word can also be used as an exclamation or reaction, thereby translating to “wild”, “insane” or “bonkers”.
In modern Danish youth culture, sindssygt is frequently reduced to just sinds .
The word is formed by joining the noun sind (mind, from Old Norse/Germanic roots) with the adjective syg (sick, which comes from “siuks”, a word preserved in 4th-century Gothic translations of the Bible).
The term sinddsygt entered the Danish language in the 1800s as a formal psychiatric and clinical term for mental illness, replacing older words like galskab (madness) or afsind . Prior to the 1800s, the mental disturbances referred to as galskab and afsind were treated socially or religiously.
From the mid-to-late 20th century, modern medicine shifted to more neutral terms such as psykotisk (psychotic) or psykisk syg (mentally ill). Sindssygt dropped out of official medical terminology and instead migrated into casual speech as an exaggeration following the same linguistic pattern as English words like “mad,” “crazy,” or “insane”.
Relying solely on standard textbook intensifiers like meget ("very") can sound stiff, boring and repetitive. Danes use sindssygt , sygt , or vildt constantly in informal speech.
