[3] From west to east these languages are Ngadha, Nage, Keo, Ende, Lio, and Palu'e.
[4] Djawanai (1983) precises that Ngadha somewhat deviates from Austronesian norms, in that words do not have clear cognates and the grammatical processes are different;[5] for example, the Austronesian family of languages makes an abundant use of prefixes or suffixes (which form new words by adding extensions either before or after root-words, such as [per-]form or child[-hood]), whereas the Ngadha language uses no prefixes or suffixes.
[8] It is never stressed and does not form sequences with other vowels except where glottal stop has dropped (e.g. limaessa 'six', from lima 'five' and 'essa 'one').
Glottal stop contrasts with zero[clarification needed] in initial position, as in inu 'drink', or 'inu 'tiny'.
Examples are emma [mma] 'father', emmu [mmu] 'mosquito', enna [nna] 'sand', Ennga [ŋŋa] (name), ebba [bba] 'swadling sling', ebbu [bbu] 'grandparents', Ebbo [bbo] (name), erro [rro] 'sun' – also in medial position with voiceless consonants, as in limaessa [limassa] 'six'.
