How to Use Contractions

Co-authored by Stephanie Wong Ken, MFA

Last Updated: October 3, 2024 References

In common speech, we use contractions all the time. “Don’t run in the hallways,” “I can’t get this bottle open,” “She won’t stop texting during the show.” Many grammar experts argue for the use of contractions in writing, especially in a casual email, a letter, or a piece of fiction. But some teachers and professors may frown on contractions in essay writing and more formal pieces of writing, like an official document or a business letter. In common speech and in writing, contractions can be a good way to say more with less, and to condense your sentences so they have a more informal, colloquial tone.^{[1]

1
Understand when it is appropriate to use a contraction. From a technical standpoint, contractions are not necessary in written English. The grammatically correct way to write requires the full version of every word. Contracting, or shortening words, should only be done for stylistic purposes and for specific types of writing.^{[2]

- If you are writing something where you are “talking” directly to your reader, you may use contractions. Writing a casual email or letter to a friend or someone you know well on a personal level would be an appropriate time to use contractions to keep your language from sounding stuffy or too formal. Contractions often create a friendly and casual tone when used in writing.
- If you are writing dialogue in a play or a novel, you may use contractions to show how a certain character speaks to other characters. This also extends to school assignments when you are creating a scene for a play or writing a short story.
- If you are creating a slogan or an advertisement, you may use contractions to keep the phrase short and to the point.
- Avoid using contractions in formal documents like cover letters, medical documents, or legal documents. The only time you will use contractions in an academic essay is when you are quoting sources that use contractions. Some teachers and professors may be less rigid on the “no contractions” in an essay rule. Ask your teacher about this before you hand in an essay full of contractions.

Use an apostrophe to make a contraction. When you create a contraction, you are taking two words and putting them together. You then insert an apostrophe to replace certain letters in the two words.^{[3]

- For example: “he is” is contracted to: “he’s”. “They are” is contracted to: “they’re”.
- You use contractions in a sentence to shorten the phrase and give it a less formal tone. For example: “They are playing together.” When you use a contraction, you combine “they” and “are”. You then replace the “a” with an apostrophe. The sentence becomes: “They’re playing together.”
- You can also use contractions in questions. For example, “Where did they go?” When you use a contraction, you combine “where” and “did” together. You then replace the “i” with an apostrophe. “Where’d they go?”

Recognize the difference between “it’s” and “its”. One of the most misused contractions is the contraction “it’s”. “It’s” is the contracted form of “it is” or “it has”. It is never the possessive form of “it”. Use the context of the sentence to determine if you need to use an apostrophe or no apostrophe for “it”.^{[4]

- For example: “It’s late.” You use an apostrophe because this is the contracted form of “it is”. “It’s been a lovely evening”. This is the contracted form of “it has”.
- But a sentence like: “The cat licked its tongue” does not require an apostrophe for “its” because the “its” is possessive in the sentence. “It” refers to “the cat” and is possessive, so it does not require an apostrophe. “The cat licked it’s tongue” would mean “The cat licked it is tongue” or “The cat licked it has tongue” and this is clearly incorrect.

Understanding the Different Types of Contractions

1
Familiarize yourself with positive contractions. Positive contractions are used often in common speech and in casual writing. They are often used when a pronoun, such as “I” is next to a verb, such as “is”. The most common positive contractions include:^{[5]

- “I’m”: contracted form of “I am”
- “I’ve”: contracted form of “I have”
- “I’ll”: contracted form of “I will”
- “I’d”: contracted form of “I would/ I should/ I had”
- “You’re”: contracted form of “you are”
- “You’ll”: contracted form of “you will”
- “You’d”: contracted form of “you had/ you would”
- “He’s”: contracted form of “he has/ he is”
- “He’ll”: contracted form of “he will”
- “He’d”: contracted form of “he had/he would”
- “She’s”: contracted form of “she has/she is”
- “She’ll”: contracted form of “she will”
- “She’d”: contracted form of “she had/she would”
- “It’s”: contracted form of “it has/it is”
- “It’ll”: contracted form of “it will”
- “We’re: contracted form of “we are”
- “We’ve”: contracted form of “we have”
- “We’ll”: contracted form of “we will”
- “We’d”: contracted form of “we had/ we would”
- “They’re”: contracted form of “they are”
- “They’ve”: contracted form of “they have”
- “They’ll”: contracted form of “they will”
- “They’d”: contracted form of “they had/they would”
2
Keep in mind the double meanings of some positive contractions. Some contractions, such as “he’d” could be the contracted form of either “he would” or “he had”. The context of the sentence will help you determine which meaning is implicated by the contraction. Always read the entire sentence to figure out what contraction is being used.^{[6]

- For example: “She’d like to go to the store.” This is the contraction of “She would like to go to the store” as it is the only grammatically correct option. “She had like to go to the store” is clearly incorrect.
- “She’d completed the work by the time I arrived.” This is the contraction of “She had finished the work by the time I arrived” as it is the only grammatically correct option. “She would finished the work…” is clearly incorrect.
- As well, the contraction “‘s”, the contracted form of “is” or “has” can be used with pronouns and it can be used with nouns, names, question words, and words like “here” and “there”. For example: “The plane’s late.” “Joan’s left.” “What’s the score?” “There’s the dog.” “Here’s your receipt.”
3
Identify negative contractions. Negative contractions are when you take a verb, such as “are” and combine it with “not”. The apostrophe is then used to replace the “o” in “not” so it becomes “n’t”. Examples of negative contractions are:^{[7]
X
Research source}
- “Aren’t”: contracted form of “are not”
- “Can’t”: contracted form of “cannot”
- “Couldn’t”: contracted form of “could not”
- “Daren’t”: contracted form of “dare not”
- “Didn’t”: contracted form of “did not”
- “Doesn’t”: contracted form of “does not”
- “Don’t”: contracted form of “do not”
- “Hasn’t”: contracted form of “has not”
- “Haven’t”: contracted form of “have not”
- “Hadn’t”: contracted form of “had not”
- “Isn’t”: contracted form of “is not”
- “Shouldn’t”: contracted form of “should not”
- “Wasn’t”: contracted form of “was not”
- “Weren’t”: contracted form of “were not”
- “Won’t”: contracted form of “will not”
- “Wouldn’t”: contracted form of “would not”
- Other negative contractions like “mayn’t” (contracted form of “may not”), “mustn’t” (contracted form of “must not”) and “needn’t” (contracted form of “need not”) are considered outdated contractions. They are not used in common speech and are often not used in written language.
4
Understand the double use of some negative contractions. When you are using the verb “to be” in a sentence and you are trying to create the negative form, there are two possible options. For example: “we are not” could be contracted to “we aren’t” or “we’re not”. “She is not” can be contracted to “she isn’t” or “she’s not”. “They are not” can be contracted to “they aren’t” or “they’re not”.^{[8]
X
Research source}
- The exception is “I am not.” It can only be contracted to “I’m not”. Do not contract “I am not” to “I’m n’t” or “I am n’t”. In English, the contractions “‘s” and “‘re” usually appear after pronouns. For example: “We aren’t ready yet.” “He’s not a good man.”
- You may put a contraction at the end of a question, such as: “You’ve spoken to Mark, haven’t you?” But if you are putting “am not” at the end of the question, it should be contracted to “aren’t”. For example: “I’m early, aren’t I?”
5
Apply only one contraction in a sentence. It is grammatically incorrect to put more than one contraction in a sentence that is not a question. For example: “He’s not here”, instead of “He’s n’t free”.^{[9]
X
Research source}
- Keep in mind positive contractions should appear in the middle or the beginning of the sentence, never at the end of a sentence. For example: “I think we’re lost.” “Yes, I think we are.” You would not write, “Yes, I think we’re”.
6
Use informal contractions in casual conversation only. Informal contractions like “gonna” (contracted form of “going to”), “wanna” (contracted form of “want to”) and “gimme” (contracted form of “give me”) are not appropriate for formal or informal writing, and should be restricted to casual conversation only. The exception is if you are writing dialogue in a novel, play, or other work of fiction where characters use informal contractions when they are speaking to each other. Informal contractions are not considered proper English and are often frowned upon even in casual speech.^{[10]

- Other informal contractions include “whatcha” (contracted form of “what are you”), “ain’t” (contracted form of “am not”) and “gotta” (contracted form of “got to”).

Using Contractions in a Sentence and a Paragraph

1
Apply contractions to a sentence. Choose one to two sentences from a book or a piece of writing that do not contain contractions. Adjust the sentences so they have properly contracted words.^{[11]

- For example: “I am going to the store to buy some eggs. We are having omelets for breakfast.” If you adjust the sentences to have contractions: “I’m going to the store to buy some eggs. We’re having omelets for breakfast.”
- Another example might use positive and negative contractions. For example: “You did not go to the store in time. I am making pancakes instead.” The sentence with contractions would be: “You didn’t go to the store in time. I’m making pancakes instead.”
2
Distinguish between the use of “it’s” and “its” in a sentence. Tackle one of the most common mistakes in written English by testing your ability to use “it’s” and “its” properly in a sentence.^{[12]
X
Research source}
- For example: “It is time to party.” The sentence with the contraction would be: “It’s time to party” as “it’s” is the contracted version of “it is”. “The horse lifted its head.” This sentence does not need an apostrophe as the “it” is possessive and not a contraction.
3
Use contractions in a paragraph. Amp up your ability to use contractions correctly by making a list of things you are going to do during your school day. Use “I” or “he” or “she” to describe each action you are going to do today. Don’t use any contractions in your paragraph about your day. Then, read it over and adjust it so it has contractions.
- For example: “I am going to wake up and brush my teeth. Then, I will get dressed and curl my hair. My mom is not going to be happy because I am late for the bus. She will tell me not to eat breakfast and to run for the bus instead. On my walk to school, I will see my friend Lola. Lola is one of my best friends at school.”
- If you adjust this paragraph so it has contractions: “I’m going to wake up and brush my teeth. Then, I’ll get dressed and curl my hair. My mom isn’t going to be happy because I’m late for the bus. She’ll tell me not to eat breakfast and to run for the bus instead. On my walk to school, I’ll see my friend Lola. Lola’s one of my best friends at school.”

Question

Why can't I say, "He's a beard" for "He has a beard"?

Community Answer

Because that would be confusing, since "he's" can also mean "he is." When we say that "he's" can mean "he has," we don't mean it in the sense of ownership (as in "he has a beard"). We mean the case where "has" is a helping verb (as in "he's gone home" -- "he has gone home.") It could work for "he has" when quoting informal speech though.

Question

"I've to go home." Is this appropriate to use?

Community Answer

No. Say "I have to go home" instead. Say "I've" when you're using "have" as a "helping" (auxiliary) verb. An example: "I've gone to school" means "I have gone to school."

Question

What are the uses of contraction?

Donagan

Top Answerer

A contraction consists of two words shortened (contracted) into one word. It reflects the way people often speak. "Do not" becomes "don't." "Will not" becomes "won't." "I am" becomes "I'm." "You are" becomes "you're." "She is" becomes "she's."
