Pali na (9)
According to Davids and Stede’s Pali-English Dictionary, na refers to the negative and adversative particle “not.” It also has an etymological relationship with other Indo-European languages, denoting the similar meaning “not.” For instance, Vedic na, Indo-Germanic *ne, Latin ne (as in n' unquam), Gothic ni, Sanskrit na ca, Latin neque, Gothic nih, Sanskrit nā, and Indo-Germanic *nē (cf. Latin and Gothic nē) are analogous to Pali na. This na traces its origin to the Tamil root al through the transformation of al > a > an > ná > na. The following words, related to Pali na, also originate from Tamil al.
natthika, one who professes the motto of natthi, a sceptic, nihilist. natthika-diṭṭhi, scepticism, nihilistic view, heresy. natthika-vāda, one who professes a nihilistic doctrine. natthitā, nihilism. natthibhāva, non-existence. neka, not one, several, many. neva, see na; (being) neither perception nor non-perception. no, negative and adversative particle; neither, nor, but not, surely not, indeed not.
