Tokens are surface tokens (Spanish `vámonos` is one), words are syntactic words (`vamos` + `nos`); multiword tokens are those split into several words; empty nodes are the `N.M` nodes of the enhanced graph. Splits train, dev are absent from the release.

## Summary

> This is an Apurinã treebank consisting of sentences from a grammatical description of the language by Maília Fernanda.

## Introduction

> The initial release contains 70 annotated sentences. This is the first treebank in a language from the Arawak family. The original interlinear glosses are included in the tree bank, and their conversion into a full UD annotation is an ongoing process. The sent_id values (e.g.: FernandaM2017:Texto-6-19) are representative of the collector, year of publication, text identifier and the number of the sentence in order from the original text.
