Do you capitalize aunt in a sentence? The answer depends on how the word is used.
Sometimes, Aunt should begin with a capital letter. Other times, aunt should stay lowercase. This can be confusing because the same word can be used as both a family title and a general relationship word.
The simple rule is this: capitalize Aunt when it is used as part of a name or when it replaces a person’s name. Use lowercase aunt when it refers to a family relationship in a general way.
For example, you should write Aunt Jenna with a capital A because it is used like a name. But you should write my aunt Jenna with a lowercase a because the word aunt is describing the relationship.
Let’s look at the rules, examples, and common mistakes so you can use Aunt and aunt correctly every time.
Do You Capitalize Aunt?
Yes, you capitalize Aunt in some cases, but not all the time.
You should capitalize Aunt when it comes directly before a person’s name or when it is used as a substitute for a name.
Correct Examples
- I visited Aunt Jenna yesterday.
- Aunt Maria is coming to dinner.
- We called Aunt Sarah on her birthday.
- Thank you, Aunt, for helping me.
In these sentences, Aunt is being used like a title or name, so it is capitalized.
However, you should not capitalize aunt when it is used as a common noun.
Correct Examples
- My aunt lives next door.
- I have an aunt in Canada.
- Her aunt is a teacher.
- The aunt I admire most is very kind.
In these examples, aunt is simply describing a family relationship, so it stays lowercase.
When to Capitalize Aunt
Capitalize Aunt when it is used as a proper title before a person’s name. In this case, it works like part of the person’s name.
Examples
- Aunt Jenna baked cookies for us.
- I went shopping with Aunt Lisa.
- Aunt Maya always gives good advice.
- We are visiting Aunt Rebecca this weekend.
In each sentence, Aunt comes directly before a name. That makes it part of the name or title, so it should be capitalized.
You can think of it the same way you would capitalize words like Doctor, Professor, or Grandma when they are used with a name.
More Examples
- Aunt Rachel called me this morning.
- I gave the gift to Aunt Olivia.
- Aunt Emily lives near the beach.
- We had lunch with Aunt Clara.
All of these examples are correct because Aunt is being used as a family title before a name.
Capitalize Aunt When It Replaces a Name
You should also capitalize Aunt when it is used instead of the person’s name. This often happens when speaking directly to your aunt.
Examples
- Thank you, Aunt, for the gift.
- Are you coming with us, Aunt?
- I missed you, Aunt.
- Can you help me, Aunt?
In these sentences, Aunt is being used like a personal name. Because it replaces the person’s actual name, it should be capitalized.
This rule is similar to how people capitalize Mom, Dad, Grandma, and Grandpa when those words replace names.
Examples
- I asked Mom for help.
- I called Dad after school.
- Thank you, Grandma.
- I asked Aunt if she wanted tea.
In each example, the family word is used like a name, so it is capitalized.
When Not to Capitalize Aunt
Do not capitalize aunt when it is used as a general family relationship word.
This usually happens when words like my, your, his, her, our, their, an, or the come before it.
Examples
- My aunt is very kind.
- Your aunt called earlier.
- His aunt lives in Texas.
- Her aunt is a doctor.
- Their aunt came to visit.
- I have an aunt who lives nearby.
- The aunt who lives next door is friendly.
In these sentences, aunt is not being used as a name. It is only describing the person’s relationship to someone, so it should be lowercase.
Aunt Jenna or My Aunt Jenna?
This is one of the most common areas of confusion.
Both phrases can be correct, but they are written differently.
Correct
- Aunt Jenna is coming over.
- My aunt Jenna is coming over.
In the first sentence, Aunt Jenna is used like a name, so Aunt is capitalized.
In the second sentence, the word my comes before aunt. This makes aunt a general relationship word, so it should be lowercase.
More Examples
Correct:
- I called Aunt Jenna.
- I called my aunt Jenna.
Correct:
- Aunt Maria gave me a book.
- My aunt Maria gave me a book.
Correct:
- We visited Aunt Lisa.
- We visited our aunt Lisa.
The difference is small, but it matters in proper grammar.
Is Aunt a Proper Noun?
The word Aunt can act like a proper noun, but it is not always a proper noun.
It becomes a proper noun when it is used as a name or title.
Proper Noun Use
- Aunt Clara is visiting.
- I asked Aunt to help me.
In these examples, Aunt works like a name, so it is capitalized.
Common Noun Use
- My aunt is visiting.
- I asked my aunt to help me.
In these examples, aunt is a common noun because it names a general family relationship.
Common Mistakes with Aunt Capitalization
Many writers capitalize aunt when it should be lowercase. Others forget to capitalize it when it is part of a name.
Here are some common mistakes.
Incorrect
- I visited aunt Jenna yesterday.
- My Aunt Jenna lives nearby.
- I have an Aunt in New York.
- The Aunt who lives next door is very nice.
Correct
- I visited Aunt Jenna yesterday.
- My aunt Jenna lives nearby.
- I have an aunt in New York.
- The aunt who lives next door is very nice.
The easiest way to avoid mistakes is to check whether aunt is being used as a name or as a relationship word.
Capitalize Aunt with a Name
Always capitalize Aunt when it comes directly before a name.
Examples
- Aunt Bella
- Aunt Susan
- Aunt Grace
- Aunt Nora
- Aunt Emma
Now look at these phrases:
- my aunt Bella
- your aunt Susan
- her aunt Grace
- their aunt Nora
- our aunt Emma
In these examples, aunt is lowercase because it comes after a possessive word like my, your, her, their, or our.
Do You Capitalize Aunt and Uncle?
The same rule applies to aunt and uncle.
Capitalize them when they are used with a name or as a name. Use lowercase when they are general family relationship words.
Correct Examples
- Aunt Mary and Uncle John are coming over.
- I called Uncle David yesterday.
- My aunt and uncle live in Florida.
- Their uncle is very funny.
- Her aunt is visiting next week.
Incorrect Examples
- My Aunt and Uncle live in Florida.
- I called uncle David yesterday.
- Their Uncle is very funny.
If the word is part of a name, capitalize it. If it is only describing a relationship, use lowercase.
Quick Rule to Remember
Here is the easiest rule:
Capitalize Aunt when it acts like a name.
Use lowercase aunt when it describes a relationship.
Ask yourself this question:
Can I replace “Aunt” with the person’s name?
If yes, capitalize it.
Example:
- I called Aunt Jenna.
- I called Jenna.
This works, so Aunt Jenna is capitalized.
Now look at this sentence:
- I called my aunt Jenna.
Here, aunt describes who Jenna is. It is not being used as the name itself, so it stays lowercase.
More Correct Examples
Here are more examples to help you understand the rule clearly.
Capitalized Aunt
- Aunt Sophie made dinner.
- I gave flowers to Aunt Rose.
- Aunt Jane helped me with my homework.
- We invited Aunt Laura to the party.
- I asked Aunt if she wanted coffee.
Lowercase aunt
- My aunt Sophie made dinner.
- I gave flowers to my aunt Rose.
- My aunt helped me with my homework.
- We invited my aunt to the party.
- I have an aunt who lives next door.
