Assorted Initial Trees

Trees that are not part of the tree families are generally gathered into several files for convenience. The various initial trees are located in lex.trees. All the trees in this file should begin with an $\alpha$, indicating that they are initial trees. This is followed by the root category which follows the naming conventions in the previous section (e.g. n for noun, x for phrasal category). The root category is in all capital letters. After the root category, the node leaves are named, beginning from the left, with the anchor of the tree also being capitalized. As an example, the $\alpha$NXN tree is rooted by an NP node (NX) and anchored by a noun (N).
