Qaqet is a non-Austronesian language, spoken by about 15,000 people in East New Britain, Papua New Guinea. In the remote inland, children acquire Qaqet as their first language. Much of what we know about child‑directed speech (CDS) stems from children living in middle‑class, urban, industrialised contexts. This book combines evidence from different methods, showing that the features typical for speech to children in such contexts are also found in Qaqet CDS.
