Have you ever seen a sentence start with a big letter? That big letter is helping your eyes know, "This is the beginning!" Writers use capital letters to make writing clear and easy to read. One very important rule is to capitalize the first word in a sentence. Another important rule is to capitalize the word I when you are talking about yourself.
A capital letter is a big letter. It is also called an uppercase letter. For example, A is a capital letter, and a is a lowercase letter. We do not use big letters for every word, but we use them in special places.
Capital letter means a big letter, like B, M, or T. Writers use capital letters at the beginning of sentences and for the word I.
Capital letters help readers. They show where a sentence begins. They also make writing look neat and correct. When you write, a capital at the beginning is like opening the door to your sentence.
A sentence is a group of words that tells a complete idea. The first word in every sentence starts with a capital letter.
Look at these examples:
The dog runs.
We like to play.
My mom reads a book.
Can you jump?
Wow, that is big!
Each sentence begins with a capital letter. It does not matter if the sentence is telling, asking, or showing strong feeling. The first word still begins with a capital letter.
Beginning of a sentence
When a new sentence starts, the first word gets a capital letter right away. This helps the reader see where one idea starts. After an ending mark such as a period, question mark, or exclamation point, the next sentence begins with a capital letter.
Here are some more sentence beginnings:
I see a bird.
The sun is hot.
Do you want juice?
Look at the kite!
There is one very special word in English: pronoun I. The word I means you are talking about yourself. It is always a capital letter.
Look at these examples:
I am happy.
My dad and I went to the park.
Can I have a turn?
I like apples.
Even if the word I is in the middle of a sentence, it is still capitalized. We do not write i when we mean the word I.
Correct and incorrect writing
Step 1: Read the sentence with a mistake.
i like cats.
Step 2: Fix the beginning of the sentence and the word I.
I like cats.
Step 3: Read it again to check.
The sentence now starts correctly, and the word I is a capital letter.
This rule is easy to remember: if you mean yourself, write I, never i.
Sometimes a sentence has a small capitalization mistake. Good writers learn to spot it.
Wrong: the fish is blue.
Right: The fish is blue.
Wrong: my sister and i can sing.
Right: My sister and I can sing.
Wrong: can i go?
Right: Can I go?
The word I is only one letter long, but it is always written as a capital letter. That makes it a very special word in English writing.
When you finish writing a sentence, look back at the beginning. Ask, "Did I use a capital letter?" Then look for the word I. Ask, "Did I capitalize I?"
You can see capitals in storybooks, signs, cards, and messages. When you read, notice the big letter at the start of each sentence. When you write, use the same rule in your own work.
If you write, "I see my dog. I pet my dog," both sentences begin with capital letters, and both uses of the word I are capitalized too. That makes your writing clear and easy to read.
Using capitals is part of good writing. These little letters do a big job. They help your reader understand your sentences from the very first word.
