This document provides an overview of subjects and verbs in English sentences. It defines subjects and verbs as the basic building blocks, and provides simple methods to identify them using questions like "who/what is the sentence about?" and "what does the sentence say about the subject?". It also discusses different types of fragments that can occur when subjects or verbs are missing, such as dependent word fragments, -ing and to fragments, added detail fragments, and missing subject fragments. Ways to correct each type of fragment are presented.
