Your Sincerely or Yours Sincerely? explains a common grammar issue in emails and letters with proper usage and confidence. Many students, professionals, job seekers, and fluent English speakers have paused while sending an email and wondered about this tiny phrase. This guide explains the right and wrong choice, helping you understand correctness, formal sign-off, and professional communication to use correctly the best ending.
From my experience in writing and reviewing professional messages, the sign-off or closing of a letter is the final part a reader may think about. A proper ending helps you sound professional, remain polite, maintain a professional tone, and leave a good impression as a last impression. Many people hit a wall when they decide how to end a message because email etiquette can feel like a walk through a minefield of uncertainty and a common mistake.
The answer may surprise you, as understanding the distinction between Your Sincerely and Yours Sincerely can clear up confusion once and for all. Choosing the correct phrase helps you avoid mistakes that can quietly weaken your credibility and allows every email to be written with greater confidence every time.
Your Sincerely or Yours Sincerely: Which One Is Correct?
The correct phrase is yours sincerely.
“Your sincerely” is incorrect because your needs a noun after it. For example, you can say:
- your letter
- your email
- your help
But you cannot end a letter with your sincerely because sincerely is not a noun. It is an adverb. So the phrase breaks the grammar rule.
By contrast, yours can stand alone. It already means something belongs to or is connected with the writer. In formal closings, yours sincerely works as a complete phrase.
The simple rule
- Your = possessive adjective
- Yours = possessive pronoun
That is the heart of the issue.
Your sincerely sounds wrong because it is missing the grammatical partner it needs. Yours sincerely works because the sentence ending is complete.
What Does “Yours Sincerely” Mean?
Yours sincerely is a formal closing used in letters and emails. It signals respect, professionalism, and politeness. It is common in British English and other varieties influenced by British letter-writing conventions.
The phrase has a traditional feel. It tells the reader that the message is polite but not overly warm. It sits in that middle space between stiff formality and friendly casualness.
In practice, it often appears in letters where you know the recipient’s name.
For example:
Dear Mr. Khan,
Thank you for your time and consideration.
Yours sincerely,
Ayesha Malik
That format feels polished and standard. It is especially common in business letters, job applications, cover letters, and formal requests.
Why “Your Sincerely” Is Incorrect
The mistake happens because English learners often see your and yours as nearly interchangeable. They are not.
Your vs. Yours
Here is the cleanest way to think about it:
- Your always comes before a noun.
- Yours stands on its own.
So these are correct:
- your car
- your idea
- your message
These are also correct:
- The car is yours.
- That idea is yours.
- This message is yours.
But your sincerely does not fit either pattern. There is no noun after your, and sincerely does not rescue the sentence. That is why the phrase is wrong.
Why people make the mistake
The error is common for a few reasons:
- Typing habits: People type quickly and rely on muscle memory.
- Autocorrect: Some devices do not catch the mistake.
- Translation influence: In some languages, closings work differently.
- Informal email habits: Quick digital writing can blur grammar rules.
- Sound, not structure: The phrase may “sound right” to the writer even when it is not.
That is why this error appears so often in cover letters, school assignments, and business emails.
When to Use “Yours Sincerely”
Use yours sincerely in formal letters and emails, especially when you know the recipient’s name.
This is the classic British-style rule:
- Dear Mr. Smith, → Yours sincerely,
- Dear Ms. Brown, → Yours sincerely,
The idea is simple. You opened the letter with a named greeting, so you close with yours sincerely.
Common situations where it fits
- Job applications
- Cover letters
- Business correspondence
- Academic letters
- Formal complaints
- Requests to institutions
- Professional follow-up messages
Example
Dear Dr. Ahmed,
I appreciate your feedback on my proposal. Your guidance helped me refine the final version.
Yours sincerely,
Sara Iqbal
That closing feels appropriate because the message is formal and the recipient is named.
American English vs. British English: How “Yours Sincerely” Is Used
This is where many people get confused. The phrase is common in British English. In American English, writers usually prefer sincerely or sincerely yours.
British English
In British letter writing, the traditional rule is:
- Dear Mr. Brown, → Yours sincerely,
- Dear Sir or Madam, → Yours faithfully,
That distinction is still widely taught and used.
American English
In American English, writers more often use:
- Sincerely,
- Sincerely yours,
- Best regards,
- Kind regards,
Americans tend to be less rigid about the old formal pairing system. Sincerely is the safest and most common choice.
Practical takeaway
If you are writing in a British style, yours sincerely is a strong formal choice.
If you are writing in American English, sincerely is usually the better default.
Your Sincerely or Yours Sincerely in Real Writing
The easiest way to understand this is to see it in context.
Correct examples
- Dear Mr. Ali,
Yours sincerely,
Nadia - Dear Ms. Turner,
Yours sincerely,
Michael - Dear Professor Lewis,
Yours sincerely,
Hassan
Incorrect example
- Dear Mr. Ali,
Your sincerely,
Nadia
That version looks wrong because your cannot stand alone there.
Another correct American option
- Dear Mr. Ali,
Sincerely,
Nadia
That version is short, standard, and widely accepted.
“Yours Sincerely” vs. “Yours Faithfully”
These two are often linked in British English, so it helps to separate them cleanly.
Yours sincerely
Use it when you know the recipient’s name.
- Dear Mr. Smith,
- Dear Dr. Jones,
- Dear Ms. Patel,
Yours faithfully
Use it when you do not know the recipient’s name.
- Dear Sir or Madam,
- Dear Hiring Manager,
- Dear Customer Service Team,
That rule is traditional British usage. It comes from the idea that a named greeting deserves a slightly more personal closing. An unnamed greeting calls for a more formal one.
Quick comparison table
| Greeting | British closing |
| Dear Mr. Brown | Yours sincerely |
| Dear Ms. Green | Yours sincerely |
| Dear Sir or Madam | Yours faithfully |
| Dear Hiring Manager | Yours faithfully |
This pattern is useful in formal applications and official letters.
“Sincerely” vs. “Sincerely Yours” vs. “Yours Sincerely”
These look similar but they do not always serve the same purpose.
Sincerely
This is the most common American closing. It is formal but simple.
Example:
Dear Ms. Lee,
Thank you for reviewing my application.
Sincerely,
Jordan Kim
It is short and clean. That is one reason it works so well in business writing.
Sincerely yours
This is a more traditional American variation. It sounds slightly more formal or old-fashioned than sincerely alone.
Example:
Dear Mr. Harris,
I appreciate your time and consideration.
Sincerely yours,
Elena Ortiz
You will still see it, but it is less common in modern everyday emails.
Yours sincerely
This is the British-style form. It is the one you use after a named greeting in formal British correspondence.
Example:
Dear Mrs. Bennett,
I am writing to confirm receipt of your documents.
Yours sincerely,
David Clarke
Easy memory trick
- Sincerely = common U.S. option
- Sincerely yours = traditional U.S. option
- Yours sincerely = common U.K. option
How Formal Should Your Closing Be?
Not every message needs the same level of formality. The right closing depends on who you are writing to and why.
Very formal
Use this for official letters, applications, and business correspondence:
- Yours sincerely
- Yours faithfully
- Sincerely
- Respectfully
Professional but friendly
Use this for workplace emails and client communication:
- Best regards
- Kind regards
- Warm regards
- Best
Casual
Use this for friends, classmates, or informal exchanges:
- Thanks
- Cheers
- Take care
- Talk soon
Choosing the wrong closing can make a message feel awkward. A job application signed “Cheers” may seem too casual. A quick note to a colleague signed “Yours faithfully” may feel oddly stiff.
Tone matters. A lot.
What “Your Sincerely” Tells the Reader
Even if the reader does not stop to analyze the grammar, the mistake can still affect how the message feels.
A wrong closing can make a letter seem:
- careless
- rushed
- less professional
- less polished
That does not mean one typo ruins everything. It does not. But in formal writing, closings carry weight. They are the last line the reader sees. Like a handshake, they leave an impression.
A clean closing tells the reader you paid attention.
Common Mistakes with “Yours Sincerely”
Here are the errors people make most often.
Using “your sincerely”
This is the central mistake.
Incorrect:
- Your sincerely,
Correct:
- Yours sincerely,
Capitalizing inconsistently
In modern email style, many writers capitalize only the first word of the closing.
Correct:
- Yours sincerely,
Also common:
- Yours Sincerely,
Both appear in real use, although the lowercase version is more common in contemporary style guides.
Forgetting the comma
Most closings in English are followed by a comma.
Correct:
- Yours sincerely,
Incorrect:
- Yours sincerely
Mixing informal and formal tone
A letter that begins formally but ends casually can feel inconsistent.
Example:
- Dear Professor White,
…
Thanks a lot!
That may be fine in some contexts, but it is too loose for highly formal writing.
A Simple Grammar Breakdown of “Your” and “Yours”
This is where the rule becomes easy to remember.
Your
Use your before a noun.
Examples:
- your book
- your office
- your answer
- your meeting
Yours
Use yours when the noun is already understood or omitted.
Examples:
- The book is yours.
- The office is yours.
- The answer is yours.
In letter closings, the noun is understood. That is why yours works.
Think of it this way:
- Your is a label.
- Yours is a complete package.
That little shift changes everything.
Examples of Correct Letter Closings
Here are practical examples for different situations.
Formal job application
Dear Hiring Manager,
I am excited to apply for the role and believe my experience matches your needs well.
Yours faithfully,
Fatima Noor
This works in British English because the recipient is not named.
Formal letter to a named person
Dear Mr. Walker,
Thank you for taking the time to review my proposal. I appreciate your thoughtful response.
Yours sincerely,
Omar Hassan
American business email
Dear Ms. Carter,
Thank you for your message. I’ve attached the requested file below.
Sincerely,
Leah Johnson
Semi-formal professional note
Dear Daniel,
It was great speaking with you earlier. I look forward to our meeting next week.
Best regards,
Priya Shah
Each closing matches the tone and the audience.
Case Study: Choosing the Right Closing in a Cover Letter
Imagine two applicants applying for the same role.
Applicant A
Dear Hiring Manager,
I am writing to express my interest in the marketing coordinator position.
Yours sincerely,
Aaron Blake
Applicant B
Dear Hiring Manager,
I am writing to express my interest in the marketing coordinator position.
Your sincerely,
Aaron Blake
Both letters may contain strong ideas. But Applicant A looks polished. Applicant B has a grammar error in the final line.
That tiny mistake can weaken the impression, especially in formal settings where attention to detail matters. Hiring managers often skim applications fast. A clean ending helps your letter look controlled and professional.
That is the real value of learning this rule. It is not about grammar for grammar’s sake. It is about credibility.
Case Study: Email Etiquette in an International Workplace
Now picture a global team. One colleague writes in British English. Another writes in American English. A third works with clients across both systems.
British style example
Dear Ms. Evans,
Please find the updated report attached.
Yours sincerely,
Rohan Mehta
American style example
Dear Ms. Evans,
Please find the updated report attached.
Sincerely,
Rohan Mehta
Both are correct. The best choice depends on audience, region, and company culture.
In a multinational workplace, consistency matters more than personal preference. If the company uses American English in most documents, sincerely may be the safest choice. If the organization follows British conventions, yours sincerely may be expected.
Alternative Closings for Letters and Emails

The answers usually point you to the right closing.
A Quick Reference Table
| Situation | Best closing |

Why This Small Rule Matters So Much
Some people think closings are minor. They are not.
A closing is the final note of your message. It can reinforce tone, polish, and professionalism. It can also undermine them if it is wrong.
Here is what strong writing does:
- It respects the reader.
- It avoids obvious mistakes.
- It matches the expected tone.
- It feels natural in context.
That is why yours sincerely matters. It may be a tiny phrase. But small phrases carry big signals.
How to Remember the Correct Form
A few memory tricks help:
Trick one: “Your” needs a noun
If there is no noun after it, it is probably wrong.
- your book
- your email
- your sincerely ✗
Trick two: “Yours” can stand alone
- The book is yours.
- The message is yours.
- Yours sincerely ✓
Trick three: Think of the closing as a set phrase
In British English, yours sincerely is a fixed expression. Treat it as one unit. Do not break it apart.
Trick four: Use the greeting to guide the closing
- Named greeting → yours sincerely
- Unnamed greeting → yours faithfully
That pattern is easy to apply once you see it a few times.
