Understanding Sentence Basics: Key Grammar Notes

1 / 5
Parts of Speech Essentials
Every sentence starts with basic building blocks called parts of speech. Nouns name the people, places, and things in our world. They come in different varieties: common nouns (school, music) are general terms, while proper nouns (Mexico, Doritos) are specific named things.
Some nouns you can touch or see (concrete nouns) like rock or boat, while others represent ideas or feelings (abstract nouns) like love or friendship. When we don't want to repeat nouns, we use pronouns like I, you, she, or they to replace them.
Demonstrative pronouns like this and that help us point to specific things in our communication. These basic parts create the foundation for everything we write.
Remember this! Every sentence needs at least one noun (or pronoun) to name what the sentence is about. Without this, you don't have a complete thought!
Sentence Structure Fundamentals
Nouns and pronouns typically serve as the subject of a sentence—the who or what the sentence talks about. For example, in "Molly and Flor ride their bikes to school," Molly and Flor are the subjects. The predicate (ride their bikes to school) tells what the subjects are doing.
A sentence must have both a subject and a verb to be complete. Without both, you have a fragment, which is an incomplete thought. Examples of fragments include "red apples," "climbing the tree," or "into the water"—these aren't complete sentences!
An actual sentence is an independent clause—a group of words with a subject and verb that expresses a complete thought. This completeness is what separates real sentences from mere fragments.
Quick Tip: Test if you have a complete sentence by asking: "Who or what is doing something?" (subject) and "What are they doing?" (verb). If both questions can be answered, you probably have a complete sentence!
Understanding Clauses
Basic sentences are independent clauses that stand alone, like "Molly and Flor ride their bikes to school." However, many sentences include dependent clauses that add information but can't stand alone as complete thoughts.
Dependent clauses often begin with subordinate conjunctions like since, while, as, because, or if. For example: "While other kids wait for the bus, Molly and Flor ride their bikes to school." The first part can't stand alone—it depends on the rest of the sentence.
There are many subordinating conjunctions to know, including after, although, because, before, even though, unless, until, when, and whenever. These words signal that the clause needs more information to make complete sense.
Pro Writing Move: Using dependent clauses adds sophistication to your writing by showing relationships between ideas. Try starting some sentences with "because," "although," or "when" to vary your style!
Types of Sentences
Sentences come in different patterns that help add variety to your writing. A simple sentence contains just one independent clause, like "Green apples taste tart." It communicates one complete thought.
When you combine an independent clause with a dependent clause, you create a complex sentence: "Green apples taste tart which means they are sour." The dependent clause adds extra information but couldn't stand alone.
A compound sentence joins two or more independent clauses that could each be their own sentence. This creates longer, more sophisticated expressions that connect related ideas.
Sentence Power-Up: Varying your sentence types keeps your writing interesting! If you notice you're using too many simple sentences in a row, try combining some into compound or complex sentences for better flow.
Creating Compound Sentences
You can create compound sentences in two main ways. First, you can use a comma plus a coordinating conjunction (for, and, nor, but, or, yet, so). For example: "Sharks attack prey quickly, but some dolphins can escape them."
The second method uses a semicolon between independent clauses: "Sharks attack prey quickly; some dolphins can escape them." Both methods connect complete thoughts that are related to each other.
For even more sophisticated writing, you can create compound-complex sentences that contain multiple clauses of different types. For example: "Movies entertain audiences when they are interesting, and they inspire the viewers." These sentences show advanced relationships between multiple ideas.
Writing Challenge: Try identifying different sentence types in your favorite book or article. Then practice writing one example of each type using topics from your own life!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️
