root
: root
The root
grammatical relation points to the root of the sentence. A
fake node ROOT
is used as the governor. The ROOT
node is indexed
with 0, since the indexing of real words in the sentence starts at 1.
There is just one node with the root
dependency relation in every
tree. If the main predicate is not present (due to
ellipsis)
and there are
multiple orphaned dependents, the leftmost dependent is promoted to
the head (root) position and the other orphans are attached to it.
An example sentence-like segment that lacks the main verb: И что он на это ? “And what [does] he [say] to it?”
