The Tolai language, or Kuanua, is spoken by the Tolai people of Papua New Guinea, who live on the Gazelle Peninsula in East New Britain Province. (This language is often referred to in the literature as Tolai. However, Tolai is actually the name of the cultural group. The Tolais themselves refer to their language as a tinata tuna, which translates as "the real language". Kuanua is apparently a word in Ramoaaina meaning "the place over there".)
Unlike many languages in Papua New Guinea, Tolai is a healthy language and not in danger of dying out to Tok Pisin, although even Tolai suffers from a surfeit of loanwords from Tok Pisin, e.g. the original kubar has been completely usurped by the Tok Pisin braun for brown or the Tok Pisin vilivil for bicycle has replaced the former aingau. It is considered a prestigious language and is the primary language of communication in the two major centers of East New Britain: Kokopo and Rabaul.
Tolai lost the phoneme /s/. For instance, the word for 'sun' in closely related languages of South New Ireland is kesakese, and this has been reduced to keake in Tolai. However, /s/ has been reintroduced through numerous loanwords from English and Tok Pisin.
