Yamdena is an Austronesian language of eastern Indonesia. Although many language materials are available, the language has received very little scientific attention. In this article, I present the Yamdena corpus, which includes glossed legacy materials and original fieldwork. I also give an up-to-date introduction to Yamdena grammar, sketching its phonology, word classes, pronouns, nouns and noun phrases, possessive marking, verbs and verbal inflection, some clausal syntax, multi-verb constructions, and clause coordination.
