This paper offers an overview of the Trinitario dialect of Mojeño, an Arawak language. It is spoken in Bolivia by several thousand speakers. The paper first gives some general information on the Mojeño language and people. It then describes the phonology of the language (vowels, consonants, syllable, stress, morphophonemics, orthography), the parts-of-speech, the morphology (transcategorial, nominal, verbal, word-class modifying), and the syntax (nominal phrase, predicate types, constituent order, negation and questions, complex sentences). It ends with the transcription of a piece of spontenous discourse, with its glosses and translation.
