Grammar is like the rules that we follow when we talk, read, or write so that we can understand each other better. Just like when we play a game, there are rules to follow so that everyone can enjoy and have fun playing together.
For example, when we speak, we use different words to show who is doing the action or what is happening. This is called a sentence. A sentence is made up of different parts, like a puzzle. Just like how we have to put the puzzle pieces together to make a picture, we have to put the sentence parts together in a certain way to make a complete sentence.
There are different types of sentence parts, like nouns, verbs, adjectives, and adverbs, and they each have a different job to do. For instance, a noun is a person, place, or thing, like a dog or a park. A verb is what the noun is doing, like running or playing. An adjective describes the noun, like a big dog or a green park. And an adverb describes how the verb is done, like running quickly or playing happily.
But we can't just put these sentence parts anywhere we want. We have to follow the rules of grammar, just like how we have to follow the rules of a game. We have to make sure that the subject (the noun doing the action) and the verb (the action that is being done) match in number and tense. For instance, we wouldn't say "The dog runs" and "The dog runned," because "runs" matches with "dog" in present tense, while "runned" doesn't make sense.
By following the rules of grammar, we can communicate more clearly and effectively. It's like having a secret code that everyone can understand if they just know the rules. So remember, just like how we have to follow rules in a game, we have to follow the rules of grammar to make sure we can communicate and understand each other better.
