때문

Etymology
First attested in the Dictionnaire coréen-français (韓佛字典 / 한불자전), 1880, in the spelling. The word was presumably in circulation for some time before that, but may have been considered too colloquial for writing. Cognate with 🇨🇬, which may point to an earlier form. Further etymology apparently.

In the spoken language, it largely displaced Early Modern Korean, now used mainly in written language, which had itself displaced Middle Korean (> modern , now used for archaic effect).

Dependent noun

 * 1) cause

Usage notes
In contemporary Korean, this dependent noun always appears either after a noun, or after a verb nominalized with. The usual constructions are [NOUN] and [NOUN], although other forms such as [NOUN]  are still encountered.

Korean has several constructions to express causation, notably the postnominal dependent noun and the verbal suffixes  and. The connotations of, in comparison to the verbal suffixes, include:


 * a stronger emphasis on the objective fact of the causal relationship
 * incompatibility with the imperative and exhortative moods, perhaps because of the above; even in interrogatives, the construction often has a connotation of confirming if the questioner's belief about the causation is correct
 * a degree of formality not present in the suffixes: is more formal than.

Until perhaps the mid-twentieth century, it could also occur after the realis adnominal (and other derived adnominals such as, ), but this is now quaint and unusual, even ungrammatical. Hence is strongly preferred over.
