masc dat sg of mahākaccāna (noun); masc gen sg of mahākaccāna (noun)
Analysis. mahā + kaccāna; mahā = 'great' (prefix/adjective); kaccāna = descendant of Kati (a patronymic or clan name, possibly from kaccha 'armpit' or a tribal designation). The compound names one of the Buddha's principal disciples, celebrated for his ability to expand concise teachings into elaborate expositions.
Etymology. mahā (from √mah 'to grow, be great'; cognate with English much, Latin magnus) + kaccāna (an old patronymic, probably pre-Buddhist, of uncertain origin; possibly from kaccha, but more likely a proper name from the Kacchāyana clan or a similar tribal group). The epithet 'Great Kaccāna' distinguishes him from other members of his family or clan who entered the order.
