Identifying Subject & Main Verb — I can identify the subject and main verb in a sentence, including when they are separated by phrases.

Every language needs a system for organizing words into meaningful statements. For thousands of years, scholars have studied how sentences work, trying to figure out which parts are essential and which parts are extra. The idea of a subject (who or what the sentence is about) and a verb (what the subject does or is) goes back to the earliest grammarians. Understanding this pair is the foundation of reading, writing, and communicating clearly.

So why does this matter to you? When you can quickly find the subject and main verb, you can check whether your sentences make sense, fix agreement errors, and understand complex readings. The big challenge is this: in real writing, the subject and verb are often separated by phrases that describe, explain, or add detail. Learning to see past those phrases is the skill this lesson will build.

Before you can hunt for subjects and verbs, you need to know exactly what each term means. Every complete sentence in English has two required parts: a subject and a predicate. The simple subject is the main noun or pronoun that the sentence is about. The main verb (sometimes called the simple predicate) is the word or words that tell what the subject does, is, or has. Everything else in the sentence — adjectives, adverbs, prepositional phrases — adds detail but is not the core.

The diagram below shows how intervening phrases sit between the subject and the main verb. Notice that the core pair — subject and verb — is highlighted, while the phrases in between are shown as removable layers. This visual pattern appears in almost every complex sentence you will encounter.

Look at Example 3 carefully. The phrase "along with several council members" might tempt you to think the verb should be plural ("have arrived"), but the true subject is mayor — a singular noun. That's why the correct verb form is has arrived. Intervening phrases are the #1 source of subject-verb agreement mistakes, so learning to see past them is a powerful skill.

You don't need formulas for this lesson, but you do need a reliable method — a set of steps you can follow every time you face a tricky sentence. Think of this method as your personal toolkit for sentence analysis.

The 4-Step Subject-Verb Finder

1. Step 1 — Find the verb first. Ask: "What is the action or state of being in this sentence?" Look for action words (runs, built, discovered) or linking verbs (is, was, seems, becomes). If you see a helping verb (has, will, can, should), pair it with the main verb.
2. Step 2 — Cross out prepositional phrases. Prepositional phrases start with words like of, in, with, at, by, for, on, from, between, among, along with, together with, as well as. The subject is almost never inside a prepositional phrase.
3. Step 3 — Cross out appositives and interrupters. These are phrases set off by commas that rename or describe a nearby noun. Example: "My teacher, a talented artist, paints every weekend." The phrase "a talented artist" is an appositive — cross it out.
4. Step 4 — Ask "Who or what [verb]?" With the phrases removed, ask "Who or what" before the verb. The answer is your subject. Confirm that the subject and verb agree in number (singular with singular, plural with plural).

Let's also talk about compound verbs and compound subjects. When two verbs share the same subject ("She sings and dances"), both verbs are main verbs. When two subjects share a verb ("Cats and dogs play together"), you have a compound subject joined by and, which takes a plural verb. The 4-step method still works — just be aware that you might find more than one subject or more than one verb.

Not all intervening phrases look the same. The more phrase types you can recognize, the faster you'll be at stripping them away to find the subject-verb core. Below is a classification of the most common types you'll encounter in school and in everyday reading.

Notice the pattern across all five types: the subject always comes before the intervening phrase, and the verb always comes after it. If you can identify and mentally remove the phrase, the subject and verb will be standing right next to each other, making the sentence easy to analyze.

Let's apply the 4-step method to a challenging sentence. Follow along carefully, and notice how each step simplifies the sentence.

Even after learning the 4-step method, there are several common traps that students fall into. The table below compares correct identification with the most frequent mistakes so you can avoid them.

The skill of finding the subject and main verb is the gateway to more advanced grammar concepts. Once you can strip a sentence down to its core, you're ready to analyze sentence types, fix run-ons, and write with greater variety and precision.

As you move into more complex writing — essays, research papers, creative pieces — you'll encounter sentences with multiple clauses, each containing its own subject-verb pair. The good news is that the same 4-step method works for each clause individually. Mastering the basics now means you'll be ready for compound-complex sentences, subordination, and parallelism without feeling overwhelmed.

Try each problem on your own before reading the answer. Use the 4-step method: find the verb, cross out prepositional phrases and interrupters, then ask "Who or what [verb]?"
