Syntax, a linguist’s word for sentence structures, is the rule system that governs how words and phrases are arranged into clauses and sentences. Grammar, though related, is not the same as syntax. It has to do with the function (i.e., role) of words and phrases in a sentence. Syntax can be thought of as a bridge between reading fluency and comprehension. When students read text fluently, with prosody, they are parsing the text in grammatical phrases which facilitates their comprehension.
