In the business world, a simple email closing can shape your image. This is why Your Sincerely or Yours Sincerely often creates confusion for professionals, students, job seekers, and fluent English speakers sending emails.
Many people have paused before sending an email and wondered about this tiny phrase. The forms Your sincerely, Yours sincerely, Sincerely yours, and Sincerely Yours may sound similar, yet only one usually fits standard practice in English-speaking countries. In most cases, Yours sincerely is the proper way to close a letter or end a letter in a formal letter when you know the person’s name. Choosing the right words, a proper sign-off, or formal sign-off helps your message leave a positive impression on the reader. From my real-world email communication and professional writing, I’ve noticed how this small detail can strengthens communication skill, writing skill, and reader understanding, while the wrong form can quietly weaken credibility.
This guide explains the correct usage and proper form so you can use phrase correctly every time. When writing emails, letters, and messages in formal correspondence or informal correspondence, careful observation, decision-making, and understanding of subtlety and nuance matter. Following instruction, studying examples, and focusing on proper use helps you avoid mistakes and improves clarity. A polite tone, professionalism, and showing respect through the traditional way of ending a letter ensure your correspondence stays accurate, clear, and effective across various contexts and audiences. Over time, this practice enhances awareness, builds a stronger communication strategy, shapes reader perception, and contribute positively to a good impression. When you remember the proper way of using common signoff, your letter maintains right tone, your email communication reflects professionalism, and your writing in English becomes more polite, effective, and properly aligned with correct usage and standard practice.
Understanding the Meaning of “Sincerely” in Letter Closings
Before comparing Your Sincerely vs Yours Sincerely, it helps to understand the word itself.
What “Sincerely” Actually Means
The word sincerely comes from the Latin word sincerus, meaning clean, pure, or genuine. In written communication it expresses honesty and authenticity.
When you end a letter with Sincerely, you are essentially saying:
This message is written honestly and respectfully.
That is why the phrase works well in professional contexts. It sounds polite without being overly emotional.
Example
Sincerely,
John Davis
This short closing communicates professionalism, respect and clarity.

Why “Sincerely” Became a Standard Letter Ending
Over the past two centuries, business communication has gradually adopted simple and neutral closings.
Older letters often used long expressions such as:
- I remain, your humble servant
- With highest consideration
- I remain respectfully yours
These phrases sounded polite but felt overly formal for modern writing.
As business communication evolved, shorter closings became standard. Among them, Sincerely stood out because it is:
- Polite
- Neutral
- Universally accepted
- Appropriate for many situations
Today it appears in millions of professional emails and letters every day.
Your Sincerely or Yours Sincerely: Which Is Correct?
Now let’s answer the main question clearly.
“Yours sincerely” is correct.
“Your sincerely” is incorrect.
The difference lies in grammar.
Why “Your Sincerely” Is Incorrect
The word your is a determiner. It must modify a noun.
Examples:
- Your book
- Your letter
- Your message
But in the phrase Your sincerely, no noun follows your. That makes the structure grammatically incomplete.
Therefore the phrase Your sincerely is considered incorrect in formal English.
Why “Yours Sincerely” Works
The word yours is a possessive pronoun. It can stand alone without a noun.
Examples:
- The decision is yours.
- This letter is yours.
In letter closings, Yours sincerely acts as a shortened form of a longer phrase:
I remain sincerely yours.
Because of that historical structure, Yours sincerely functions correctly as a closing expression.
Quick Grammar Comparison
| Phrase | Grammar Role | Correct? | Explanation |
| Your sincerely | Determiner + adverb | ❌ Incorrect | “Your” must modify a noun |
| Yours sincerely | Possessive pronoun phrase | ✅ Correct | Works as a closing expression |
In simple terms: always write “Yours sincerely,” never “Your sincerely.”
Yours Sincerely vs Sincerely Yours
Another question often appears once people understand the first rule.
Should you write “Yours sincerely” or “Sincerely yours”?
Both forms exist. The difference mainly depends on regional writing conventions.
Usage in American English
In the United States, the most common closings are:
- Sincerely
- Sincerely yours
These versions sound natural in American business writing.
Example:
Sincerely yours,
Emily Carter
Many professionals shorten it even further:
Sincerely,
Emily Carter
Usage in British English
British writing traditionally prefers:
Yours sincerely
Example:
Yours sincerely,
Oliver Brown
The phrase appears frequently in UK business letters, academic communication and official correspondence.
Quick Comparison
| Closing Phrase | Region | Typical Use |
| Sincerely | United States | Neutral professional |
| Sincerely yours | United States | Formal letters |
| Yours sincerely | United Kingdom | Formal letters |
| Yours faithfully | UK formal letters without name |
In international communication, Sincerely is the safest choice because it works everywhere.
When to Use “Yours Sincerely” in a Letter
Understanding when to use Yours sincerely helps you write professional correspondence confidently.
When You Know the Recipient’s Name
Traditional etiquette recommends Yours sincerely when the recipient’s name is known.
Example:
Dear Mr. Thompson,
Thank you for reviewing my application.
Yours sincerely,
Laura Bennett
This structure remains common in British-style letter writing.
In Formal Business Communication
The phrase appears frequently in:
- Job applications
- Cover letters
- Official business letters
- Legal correspondence
- Academic communication
Because it sounds respectful without being overly formal.
In Institutional or Government Letters
Government offices and universities often follow traditional letter formats. In those settings, Yours sincerely remains standard.
When to Use “Yours Faithfully” Instead
Another phrase often appears alongside Yours sincerely: Yours faithfully.
The difference relates to how the letter begins.
When the Recipient’s Name Is Unknown
If you start a letter with a general greeting such as:
- Dear Sir
- Dear Madam
- Dear Sir or Madam
Then traditional etiquette suggests closing with Yours faithfully.
Example:
Dear Sir or Madam,
I am writing to inquire about the internship program.
Yours faithfully,
Daniel Cooper
Why This Rule Exists
The rule developed from older British correspondence conventions.
- Yours sincerely → when the recipient is known
- Yours faithfully → when the recipient is unknown
Although modern email writing often ignores this rule, many formal institutions still follow it.
Sincerely vs Truly vs Faithfully: When to Use Each
Professional writing offers several closing phrases. Each carries a slightly different tone.
Sincerely
Tone: Professional and neutral
Best for:
- Business emails
- Cover letters
- Academic communication
- Professional networking
Example:
Sincerely,
David Martinez
Truly
Tone: Warm but slightly formal
Best for:
- Personal letters
- Polite requests
However this phrase appears less often in modern business writing.
Faithfully
Tone: Traditional and formal
Best for:
- Official letters
- Government correspondence
Example:
Yours faithfully,
Charlotte Green

Common Mistakes People Make With Letter Closings
Many professionals accidentally weaken their message with simple closing mistakes.
Understanding these errors helps you avoid them.
Writing “Your Sincerely”
This is the most common mistake.
Because your must modify a noun, the phrase becomes grammatically incorrect.
Correct version:
Yours sincerely
Using Casual Closings in Formal Situations
Informal endings may appear unprofessional in serious contexts.
Avoid these in business letters:
- Cheers
- Later
- Take care
These phrases work better among friends.
Mixing US and UK Letter Formats
Sometimes writers combine conventions incorrectly.
Example mistake:
Dear Sir or Madam,
Thank you for your time.
Yours sincerely
According to traditional etiquette, this should be Yours faithfully.
Incorrect Punctuation
Many writers misuse punctuation after closings.
Correct format:
Sincerely,
James Parker
Incorrect:
Sincerely:
James Parker
The comma remains the standard punctuation in professional correspondence.

Professional Alternatives
These closings work well in business emails.
