-니

Etymology 1
A nineteenth-century contraction of Early Modern Korean, which it replaces, as attested by the older spelling. The uncontracted form is now written due to spelling reforms and no longer has interrogative meaning; see there for more. As expected by the etymology, could originally only combine with verbs and existential adjectives but expanded rapidly to adjectives in the early twentieth century.
