indeclinable (sandhi form): yāva + kīvaṃ + ca
Analysis. yāva (as long as, to the extent that) + kīvaṃ (how much, how far) + ca (and), a correlative compound: 'as long as and how much', meaning the full extent or duration of something.
Etymology. yāva from √yam (to hold, stretch, extend; cognate with English 'yoke' and Latin iungō); kīvaṃ from ki- (interrogative stem, like Latin quis 'who?') + -va (enclitic intensifier); ca is the conjunction 'and' (cognate with Latin -que, English 'and').
