KIO
WiktionaryText
Etymology
Esperanto ki- + -o (correlative suffix of objects)
Correlative
kio (plural kioj, accusative singular kion, accusative plural kiojn)
- what (the interrogative and relative correlative of objects)
- which
- Mi daŭrigis mian laboron, ĝis kiam iu knabo aŭ virino diris "bagus, bagus," kio signifas "tre bela."
- I continued my work, until some boy or woman said "bagus, bagus," which means "very pretty."
Usage notes
Like other correlatives of objects, and unlike English what, kio always functions as a noun, never an adjective. Like other interrogative and relative correlatives, kio can be combined with ajn, the adverbial particle of generality. Kio ajn thus means whatever.
