This grammar describes Piapoco (ISO code: pio), an Arawakan language of eastern Colombia, as it was spoken during the 1960s and 1970s. The data were gathered by Deloris Klumpp, and the grammar was drafted by Klumpp during the 1980s and 1990s; it was recently edited for publication by Barbara Hollenbach. The first part of the grammar gives an overview of person marking, basic declarative sentences, mode, and tense-aspect, followed by a description of each part of speech, along with phrases based on them. The second half treats clauses and clause combinations. Special attention is given to abstract uses of adpositions, and to the use of adpositions and adverbs to express interclausal relations, which has sometimes resulted in their development into conjunctions. The grammar is accompanied by a set of ten analyzed texts gathered from the 1960s through the 1980s by Klumpp and her husband James Klumpp.
