            Word form or punctuation symbol.
        lemma : str
            Lemma or stem (depending on the particular treebank) of word form, or an underscore if not available.
        cpos : str
            Coarse-grained part-of-speech tag, where the tagset depends on the treebank.
        pos : str

        feats : str
            Unordered set of syntactic and/or morphological features (depending on the particular treebank),
            or an underscore if not available.
        head : int
            Head of the current token, which is either a value of ID,
            or zero (’0’) if the token links to the virtual root node of the sentence.
        relation : str
            Dependency relation to the HEAD.
        phead : int
            Projective head of current token, which is either a value of ID or zero (’0’),
