Most structures in English are, however, not completely left- or completely right-branching, but rather they combine both. The following trees illustrate what can be seen as a stereotypical combination of left- and right-branching in English:
Determiners (e.g. the) always and subjects (e.g. the child) usually appear on left branches in English, but infinitival verbs (e.g. try, eat) and the verb particle to usually appear on right branches. In the big picture, right-branching structures tend to outnumber the left-branching structures in English, which means that trees usually grow down to the right.

Famous quotes containing the words full and/or trees:
“Bald as the bare mountain tops are bald, with a baldness full of grandeur.”
—Matthew Arnold (1822–1888)
“The mountain stood there to be pointed at.
Pasture ran up the side a little way,
And then there was a wall of trees with trunks;
After that only tops of trees, and cliffs
Imperfectly concealed among the leaves.”
