Other comments: Nafi or Sirak has a counting system combines the counting system based on two with tallying on hand and feet to twenty. Nafi, also known as Sirak, is an Austronesian language of Morobe Province, Papua New Guinea. Nafi is an endangered language spoken by about 200 speakers in the single village of Nambom (also known as Banzain village) in Gamiki ward, Wain-Erap Rural LLG in Morobe province. Ethnic Nafi people living in Popof village have since switched to speaking Nakama, a Trans-New Guinea language. Intermarriages frequently occur between the two villages.
