How to Identify a Subject or an Object in a Sentence

Understanding how to identify the subject and object in a sentence is fundamental for mastering English grammar. The subject is the person, place, thing, or idea that performs the action, while the object is the entity that is affected by the action. Let’s explore how to identify subjects and objects using various examples, including nouns, noun phrases, and pronouns.
