Now that you have worked through a lot of material that includes these basic patterns, and you have compared grammatically correct and incorrect sentences, write down what you think is a rule that could explain what makes a sentence grammatically correct or not. For example, you might write something like: "verbs always match nouns in number, and they usually come before the noun." In other words, make your best guess for the grammar rule that makes sense out of the pattern(s) you see in the phrases you have been working with. Review if you need to, and you might briefly check your hunches against the sentences you have been working with in this or previous modules. Keep in mind that what you're after is your hunch, not a grammar rule from a text book. Now check your hunch with the explanation of this principle in the following pattern.

Based on the patterns I have observed, my best guess for a grammar rule that explains what makes a sentence grammatically correct or not is: "Sentences must have subject-verb agreement, meaning that the verb must agree with the subject in terms of number and person." This means that if the subject of a sentence is singular, the verb must also be singular, and if the subject is plural, the verb must be plural as well. To check my hunch, I can review the sentences I have worked with. For example, in the sentence "She walks to school," the subject "she" is singular, and the verb "walks" agrees with it in both number and person. Similarly, in the sentence "They walk to school," the subject "they" is plural, and the verb "walk" is also plural to match it. These examples support the idea that subject-verb agreement is a fundamental rule of grammar that determines sentence correctness.
