Analysis. Reduplicated form of jañña (accusative of jañña, 'time' or 'occasion'), doubled for iterative emphasis: 'time after time' or 'occasion after occasion'.
Etymology. Root √jan (to be born, to happen, occasion); the noun jañña derives from this root meaning 'an occasion' or 'instance'. Cognate with Sanskrit janma 'birth' and English kin, kind (things born of the same root). The reduplication is an Indo-European device for frequency and emphasis.
