Hearing the phrase "sentence diagram," most people who were in elementary, middle, and high school (and particularly parochial schools) before the last third of the 20th century is likely to bring to mind an image such as this one.

sentence diagram

This particular set of images emerged from In pedagogy and theoretical syntax, a sentence diagram or parse tree is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more in pedagogy, where sentences are diagrammed. The term "parse tree" is used in linguistics (especially computational linguistics), where sentences are parsed. The purpose of sentence diagrams and parse trees is to have a model of the structure of sentences. The model is informative about the relations between words and the nature of syntactic structure and is thus used as a tool to help predict which sentences are and are not possible.
