It's as simple as it sounds! The subject and the verb in English sentences must agree. They must match. We go to the beach on Saturdays. If the subject is plural, you need to use a plural verb form. He goes to the beach on Saturdays. He goes. The subject is singular, so you need to use a singular verb form. And this is true, most of the time! Now, you might be thinking that you understand subject verb agreement. It's simple, it's easy, right? But it's the first thing that many English learners forget! But don't worry, there are some simple standard rules that you can use to help you. But some aspects of singular and plural noun usage make this a little more complex. So that's why I'm going to teach you some tips to master subject verb agreement in English. Before we start, I want to highlight that there are two main areas where subject verb agreement can cause you problems. The first is in your writing. And it's important to know the subject verb agreement rules and how to use them correctly so that your English writing is grammatically correct. The other is your speaking skills. Now, perhaps you feel confident that you know how to match verbs to their subject but the challenge is making that clear when you're speaking. And sometimes, you might not even know this is a problem for you. The final consonant sounds are so important to communicating clearly. But for many English learners, it's not that easy to do. Pronouncing the difference between do and does. Now if this sounds like you, then I want you to try and practise with me out loud during this lesson. Make sure you're hitting those final consonant sounds. Okay? Let's begin. In the present tense, nouns and verbs agree in opposite ways. When your subject is plural, you usually add S to show that it's plural, right? Car becomes cars. Baby becomes babies. But when your subject is plural, you do not add an S to your verb. The cars look expensive. Our noun, cars, is plural. Cars. Now our verb agrees with our subject. The cars look expensive. Now compare this to: The car looks expensive. When our noun is singular, our verb needs to include an S. In these examples, the noun and the verb agree in opposite ways. But I can already hear you saying "What about if your subject is I or you? They're singular subjects but they don't use the singular verb form." Yes, but they're an exception to the rule. Subject verb agreement rules are different when your subject is in the third-person singular. So that's when your subject is a he, a she or an it. The subjects I and you are different. Even though they're also singular nouns, they take the plural form of the verb and you just need to remember that. I like to go swimming. She likes to go swimming. Both of these subjects are singular but the verb forms are different. Now, if there is an auxiliary verb, a helping verb, in your sentence like do or does in the present simple or am, is, are, was, were in the continuous tenses or have or has in the perfect tenses then, you need to think about your subject verb agreement because the auxiliary verb becomes the agreeing verb, the verb that agrees with the subject. The dogs don't want it. The dog doesn't want it. We're going to the beach. He is going to the beach. Anna and Tony have been driving for hours. Anna has been driving for hours. Now modal verbs like may, could, will, must, should, they're also auxiliary verbs. They help the main verb in the sentence but the subject verb agreement rules are different with modal auxiliary verbs. The verb following a modal verb is never in the S form. It's always in the infinitive form. My friends might come. My friend might come. Not my friend might comes. You should come. He should come. Not he should comes. Now, English sentences are not always this simple, are they? As you add more information to your sentences, they become more complex and it might be difficult to know whether your noun is singular or plural. But just remember that the same structure and rules apply. But you need to pay close attention to where your subject is and if it's singular or plural because your verb must always match the subject regardless of the words that come in between the verb and the subject. It must always match. Do you know what an indefinite pronoun is? They're words like everybody, nobody anybody, someone. Usually indefinite pronouns take singular verbs. Everybody wants to be loved. Nobody likes to be left out. Now the subject of English sentences can be a little more complicated with compound subjects. Group nouns and relative clauses. Look at this sentence. My mum is happy for me. My mum and dad are proud of me. Two singular subjects joined by "and" means that your subject becomes plural and now your verb needs to show this. It's the same as saying that they are proud of me. So we can say that two or more singular subjects joined with "and" become a plural subject and they need a plural verb. Now look at this sentence. Peter or Paul is coming. Now in this sentence, the two singular subjects are treated as a singular subject because "or" gives us an option. We're not saying both. It's one singular noun or the other. Not both of them together. We would say Peter and Paul are coming. or Peter or Paul is coming.
