Formerly vs Formally becomes easy once you know each word’s purpose and use them correctly every time. Today you can avoid common mistakes easily. Many English learners, students, writers, and native speakers pause while typing or writing because these word pairs look identical, are pronounced identically, and sound similar.
This question often confuses people, even though both are adverbs with only one letter of difference. From my experience as a grammar guy, I have seen this confusion in professional writing, formal writing, academic papers, business documents, emails, resumes, books, and online articles almost every day.
The good news is that this is not a British English or American English issue because both are correct English words with different meanings that serve different purposes. Formerly refers to the past, while Formally relates to official actions, proper behavior, a polite manner, recognized procedures, and an official process.
Quick Answer
Formerly means previously or in the past. Use it when something had a different name, position, condition, or identity before.
Example:
“The company was formerly known as Blue Ocean Media.”
Formally means officially, properly, or according to accepted rules or traditions. Use it when something happens in an official or organized way.
Example:
“The agreement was formally approved by the board.”
The easiest way to remember:
| Word | Memory Connection | Meaning | Example |
| Formerly | Former = previous | Something from the past | “He was formerly the CEO.” |
| Formally | Formal = official | Something done officially | “She was formally introduced.” |
A quick question can help:
- Are you talking about when something happened or what something used to be? → Use formerly.
- Are you talking about how something happened or whether it followed official rules? → Use formally.
What Does Formerly Mean?
Formerly is an adverb that means previously, before now, or in an earlier period of time. It describes something that was true in the past but has changed.
The word usually appears when a person, organization, place, or thing had a different identity before.
For example:
“The stadium was formerly called Riverside Arena.”
This means the stadium had another name in the past. It does not mean the stadium was officially called that name during a ceremony. It simply describes an earlier identity.
The word formerly often connects with change. Something existed one way before and exists another way now.
Common situations where you use formerly include:
- Previous names
- Past jobs
- Old titles
- Earlier locations
- Previous ownership
- Changed conditions
Formerly Used for Previous Names
One of the most common uses of formerly appears with name changes.
Examples:
- “Facebook was formerly known as The Facebook.”
- “The city was formerly called Old Harbor.”
- “The organization was formerly named Global Education Network.”
When a company changes its brand identity, writers often use “formerly known as” to explain the connection between the old and new names.
A reader may recognize the current name but still need context about its history.
Formerly Used for Past Jobs and Roles
People also use formerly when describing previous positions.
Examples:
- “Maria Lopez is formerly the director of marketing.”
- “He was formerly a professor at Stanford University.”
- “The new advisor was formerly the company’s legal consultant.”
These sentences show that the person held that role before but does not hold it now.
A resume might use this structure:
“Formerly employed as a project manager, James now leads product development.”
The word highlights a career transition.
Formerly Used for Previous Conditions
Sometimes situations change without involving names or jobs.
Examples:
- “The building was formerly a movie theater.”
- “The farmland was formerly part of a larger estate.”
- “The website was formerly available only to members.”
In each case, something was true before but is no longer true.
What Does Formally Mean?
Formally is an adverb that means officially, properly, or in a way that follows established rules, customs, or procedures.
Unlike formerly, formally does not focus on the past. Instead, it focuses on the method, setting, or seriousness of an action.
Examples:
- “The company formally announced the merger.”
- “The students were formally recognized during graduation.”
- “The couple was formally introduced to the guests.”
The action happened in an official or organized manner.
Formally Used for Official Announcements
Businesses, governments, and organizations often use formally when sharing important information.
Examples:
- “The university formally announced the scholarship winners.”
- “The company formally launched its new product.”
- “The agency formally requested additional funding.”
These examples show that the action followed an official process.
Formally Used for Ceremonies and Events
Formal situations often involve traditions, rules, or public recognition.
Examples:
- “The ambassador was formally welcomed at the airport.”
- “The award was formally presented during the ceremony.”
- “The graduates were formally recognized by the university.”
The word suggests importance and structure.
Formally Used for Professional Behavior
People also use formally when discussing professional communication or appearance.
Examples:
- “She was formally dressed for the interview.”
- “The manager formally addressed the concerns.”
- “The lawyer formally responded to the complaint.”
The action follows expected professional standards.
Formerly vs Formally: Key Differences Explained
The easiest way to separate these words is to understand the question each one answers.
Formerly answers: “What was true before?”
Formally answers: “How was something done?”
This simple difference solves most confusion.
| Question | Correct Word | Example |
| What was the company called before? | Formerly | “The company was formerly called NovaTech.” |
| How did they announce the change? | Formally | “They formally announced the change.” |
Difference Between Formerly and Formally: Time vs Manner
The biggest difference is focus.
Formerly focuses on time.
Example:
“She was formerly a nurse.”
Meaning:
She worked as a nurse in the past.
Formally focuses on manner.
Example:
“She was formally appointed as a nurse supervisor.”
Meaning:
An official process gave her the position.
The two words may appear in similar sentences, but they describe different ideas.
Compare:
“John was formerly the company president.”
This means John used to be president.
“John was formally named company president.”
This means the organization officially gave him the title.
Difference Between Formerly and Formally: Identity vs Official Action
Another useful distinction:
- Formerly describes identity changes.
- Formally describes official actions.
Example:
“The restaurant was formerly Luigi’s Cafe.”
The restaurant had another name before.
“The restaurant was formally opened by the mayor.”
The opening ceremony followed an official process.
A simple analogy:
Think of formerly as looking backward through a photo album. It shows what something used to be.
Think of formally as watching a ceremony. It shows something happening in an official way.

Formerly vs Formally in Business Writing
Professional writing requires accuracy. A single incorrect word can change the meaning of a sentence.
Businesses often use formerly when discussing history.
Examples:
- “The company, formerly known as Digital World, expanded into new markets.”
- “The founder was formerly the company’s chief operating officer.”
Businesses use formally when discussing official actions.

Why This Matters in Professional Communication
Imagine reading a company profile that says:

The sentence creates confusion. It sounds like Microsoft officially arranged her work status.
The intended meaning is probably:
“Sarah Johnson formerly worked at Microsoft.”
That small correction changes the sentence from unclear to professional.
