Regular tree grammar

In theoretical computer science and formal language theory, a regular tree grammar is a formal grammar that describes a set of directed trees, or terms. A regular word grammar can be seen as a special kind of regular tree grammar, describing a set of single-path trees. (Wikipedia).

SUBJECTS, PREDICATES, AND TREE DIAGRAMS - ENGLISH GRAMMAR

We talk about subjects: who or what the sentence is about, and predicates: what the subject does, feels, or is. We also introduce the concept of a constituent and draw some basic tree diagrams, which are tools I will use to illustrate sentence structure for the rest of the video series. I

How do we make sense of a regular sentence, especially when they take us down the "garden path"? For example, when we see a sentence that starts with "The old man," most of us would expect the next word to be a verb. So when we read, "The old man the boat," we have to backtrack to re-evalu
