Have you ever paused while finishing a formal letter and wondered whether to write “Your Sincerely” or “Yours Sincerely”?
You’re not alone.
This small grammar question confuses students, job seekers, business professionals, and even experienced writers. At first glance, both phrases seem similar. After all, they differ by only one letter. Yet that single letter makes a significant difference.
Using the wrong sign-off can make an otherwise polished letter look unprofessional. Whether you’re writing a cover letter, business proposal, complaint letter, or formal email, choosing the correct closing helps create a positive impression.
The good news is that the rule is simple once you understand it.
In this comprehensive guide, you’ll learn the correct phrase, the grammar behind it, practical examples, common mistakes, professional alternatives, and modern email etiquette rules.
Quick Answer: Is It “Your Sincerely” or “Yours Sincerely”?
The correct phrase is:
Yours sincerely
The phrase “Your sincerely” is grammatically incorrect in standard English.
Correct Example
Dear Mr. Johnson,
Thank you for your time and consideration.
Yours sincerely,
Michael Brown
Incorrect Example
Dear Mr. Johnson,
Thank you for your time and consideration.
Your sincerely,
Michael Brown
If you remember only one thing from this article, remember this:
“Yours sincerely” is correct. “Your sincerely” is incorrect.
However, understanding why it’s correct will help you avoid similar grammar mistakes in the future.
Why This Question Matters More Than You Think
Many people assume that letter closings don’t matter much.
In reality, they matter a great deal.
The closing line serves as the final impression your reader receives. Think of it as the handshake at the end of a meeting. A strong ending reinforces professionalism. A weak ending can undermine the quality of everything that came before it.
Situations Where Correct Sign-Offs Matter
- Job applications
- Cover letters
- Academic correspondence
- Legal communication
- Business proposals
- Customer complaints
- Formal requests
- Professional networking emails
Recruiters, managers, professors, and clients often notice writing details. While a single grammar mistake won’t always ruin your chances, accuracy demonstrates attention to detail.
In competitive environments, small details often separate average communication from excellent communication.
Is “Your Sincerely” Ever Correct?
This question appears frequently in grammar forums and writing communities.
The simple answer is:
No, “Your sincerely” is not considered correct as a letter closing.
The reason lies in how the word your functions in English grammar.
Understanding “Your”
The word your is a possessive determiner.
It must normally be followed by a noun.
Examples:
- Your car
- Your book
- Your application
- Your opinion
Notice that a noun follows each use of your.
When someone writes:
Your sincerely
there is no noun after your.
As a result, the phrase becomes grammatically incomplete.
What Does “Yours Sincerely” Mean?
The phrase “Yours sincerely” is a traditional closing used in formal correspondence.
It communicates:
- Respect
- Professionalism
- Courtesy
- Genuine regard for the recipient
Historically, letter writers often used longer expressions such as:
- I remain yours sincerely
- I am sincerely yours
- Yours faithfully
Over time, these expressions became shortened. Today, “Yours sincerely” remains one of the most widely accepted formal closings in English-speaking countries.
Meaning Breakdown
| Word | Meaning |
| Yours | Belonging to you |
| Sincerely | Honestly and genuinely |
Together, the phrase expresses genuine respect toward the recipient.
Grammar Breakdown: Why “Yours” Works
Let’s examine the grammar more closely.
Understanding Possessive Determiners
Possessive determiners modify nouns.
Examples include:
| Possessive Determiner | Example |
| My | My laptop |
| Your | Your laptop |
| His | His laptop |
| Her | Her laptop |
| Our | Our laptop |
| Their | Their laptop |
Notice that each determiner requires a noun.
Understanding Possessive Pronouns
Possessive pronouns can stand alone.
Examples:
| Possessive Pronoun | Example |
| Mine | The laptop is mine |
| Yours | The laptop is yours |
| His | The laptop is his |
| Hers | The laptop is hers |
| Ours | The laptop is ours |
| Theirs | The laptop is theirs |
Because yours functions as a pronoun, it does not need a noun after it.
That is why “Yours sincerely” works correctly.

Yours Sincerely vs. Yours Faithfully
This is another area that causes confusion.
Both phrases are correct. However, they serve different purposes.

Yours sincerely,
Yours Faithfully
Use Yours faithfully when you do not know the recipient’s name.
Example:
Dear Sir or Madam,
Yours faithfully,
This rule remains especially common in British English.

UK vs. US Business Writing Rules
Interestingly, usage differs slightly between countries.
British English
British business writing tends to follow traditional conventions closely.
Rule:

This rule is taught in many schools throughout the United Kingdom.
American English
American writers often prefer more flexible sign-offs.
Common choices include:
- Sincerely
- Best regards
- Kind regards
- Respectfully
- Thank you
Although Americans still understand Yours sincerely, it appears less frequently than in British correspondence.
Comparison Table
| Closing | UK Usage | US Usage |
| Yours sincerely | Very common | Less common |
| Yours faithfully | Common | Rare |
| Sincerely | Common | Very common |
| Best regards | Common | Very common |

Modern Email Etiquette Rules
Email has changed the way people communicate.
Yet professionalism still matters.
A strong email closing creates clarity and leaves a positive impression.
Use “Yours Sincerely” When:
- Applying for jobs
- Writing government offices
- Contacting universities
- Sending formal requests
- Writing legal correspondence
Avoid “Yours Sincerely” When:
- Messaging coworkers casually
- Sending quick updates
- Chatting with friends
- Internal company conversations
In less formal situations, shorter alternatives often feel more natural.
Examples include:
- Best
- Thanks
- Kind regards
- Warm regards

The key is matching your tone to the situation.

Professional Alternatives to “Yours Sincerely”
While “Yours sincerely” remains one of the most respected formal sign-offs, it isn’t always the best choice for every situation.
Modern communication often requires a different tone. Sometimes you want to sound professional yet approachable. Other times, you may need a warmer or more authoritative closing.
The secret is choosing a sign-off that matches the relationship, purpose, and formality level of your message.
Popular Alternatives to Yours Sincerely
| Sign-Off | Formality Level | Best Used For |
| Yours sincerely | Very Formal | Cover letters, official correspondence |
| Sincerely | Formal | Business communication |
| Yours faithfully | Very Formal | Unknown recipients |
| Best regards | Semi-formal | Professional emails |
| Kind regards | Semi-formal | Business relationships |
| Warm regards | Friendly Professional | Long-term contacts |
| Respectfully | Formal | Government or authority figures |
| Best wishes | Friendly | Professional acquaintances |
| Thank you | Professional | Requests and inquiries |
| With appreciation | Professional | Gratitude-focused emails |
When “Best Regards” Works Better
Imagine you’re emailing a long-term client.
Ending with “Yours sincerely” may feel overly formal. In that case, “Best regards” strikes a better balance.
Example:
Best regards,
Jennifer Adams
When “Kind Regards” Is Ideal
“Kind regards” is one of the safest modern email closings.
It communicates professionalism without sounding stiff.
Many executives, recruiters, consultants, and managers use it daily.
When “Respectfully” Makes Sense
Certain situations call for extra deference.
For example:
- Government correspondence
- Military communication
- Appeals and formal requests
- Legal matters
In these cases, “Respectfully” can be more appropriate than “Yours sincerely.”

Common Grammar Myths About Yours Sincerely
Grammar myths spread surprisingly fast.
Let’s separate fact from fiction.
Myth: “Your Sincerely” Is Acceptable in Informal Writing
Reality: It remains grammatically incorrect regardless of formality.
The issue isn’t the level of formality.
The issue is grammar.
Myth: Americans Never Use “Yours Sincerely”
Reality: Americans understand and occasionally use it.
However, many prefer shorter alternatives such as:
- Sincerely
- Best regards
- Kind regards
Myth: “Yours Faithfully” Sounds More Professional
Reality: Neither phrase is inherently more professional.
Their use depends on the recipient.
If you know the recipient’s name, “Yours sincerely” is generally the correct traditional choice.
Myth: Email Sign-Offs No Longer Matter
Reality: Sign-offs still influence how readers perceive professionalism.
A polished ending reinforces credibility.
A careless ending can weaken an otherwise excellent message.
Why Professional Sign-Offs Influence First Impressions
Communication experts often emphasize the importance of beginnings.
Yet endings matter just as much.
People frequently remember:
- The first thing they read
- The last thing they read
Your sign-off becomes part of that final impression.
Consider two applicants with identical qualifications.
Applicant A ends a cover letter professionally.
Applicant B makes a noticeable grammar mistake.
Which candidate appears more detail-oriented?
Most hiring managers would choose Applicant A.
Small details create powerful signals.
Real-World Case Study: The Job Application
Scenario
A hiring manager receives 200 applications.
Many candidates possess similar qualifications.
One applicant writes:
“Your sincerely,”
Another writes:
“Yours sincerely,”
The hiring manager notices the error immediately.
Will the mistake automatically cause rejection?
Probably not.
However, it introduces doubt.
The manager may wonder:
- Did the applicant proofread carefully?
- Does the applicant pay attention to details?
- Would similar mistakes appear in workplace communication?
One missing letter suddenly carries greater weight.
Lesson
Professional writing isn’t just about grammar.
It’s about trust.
Accurate communication signals competence.
Real-World Case Study: Customer Complaint Resolution
Scenario
A customer submits a complaint to a company.
The letter is well-written, respectful, and professional.
The closing reads:
Yours sincerely,
The customer service manager perceives the letter as serious and credible.
Now imagine the same letter ending with:
Hey,
or
Cheers,
Those alternatives may weaken the professional tone.
Lesson
The sign-off should match the seriousness of the message.
Consistency creates credibility.
Real-World Case Study: University Admissions
Admissions officers review thousands of applications each year.
Many applicants focus heavily on grades and achievements.
However, writing quality still matters.
A properly structured letter that uses:
- Correct grammar
- Professional formatting
- Appropriate sign-offs
creates a stronger overall impression.
While “Yours sincerely” won’t secure admission by itself, it contributes to a polished application package.
As the saying goes:
“Excellence is often found in the details.”
Expert Tips for Professional Correspondence
Strong communication requires more than choosing the right sign-off.
The entire message should reflect professionalism.
Address the Recipient Properly
Use:
- Dear Mr. Smith
- Dear Ms. Johnson
- Dear Dr. Wilson
Avoid overly casual greetings in formal contexts.
Keep Your Tone Consistent
If your letter begins formally, maintain that tone throughout.
A formal introduction paired with a casual ending can feel awkward.
Proofread Before Sending
Check:
- Spelling
- Grammar
- Names
- Dates
- Attachments
Many embarrassing mistakes result from rushed proofreading.
Use Clear Paragraphs
Short paragraphs improve readability.
Large blocks of text often discourage readers.
End with Gratitude
Whenever appropriate, thank the reader for:
- Their time
- Their consideration
- Their assistance
- Their response
Gratitude strengthens professional relationships.
