Formally vs Formerly compares two near-homophones with similar spelling and pronunciation but very different meanings. Formally comes from “formal” and means something done in an official, proper, or ceremonial way. Formerly comes from “former” and means previously or at an earlier time.
From a grammar viewpoint, formally is an adverb of manner, while formerly is an adverb of time. Their root words offer an easy memory trick: remove -ly to reveal “formal” and “former.” Because both words are spelled correctly, spell-checkers and grammar tools may not notice when you choose the wrong one.
Use formally for official actions, established rules, ceremonies, protocols, or proper behavior. For example, a company may formally introduce its new CEO. Use formerly for a previous role, name, condition, or time, especially in the phrase “formerly known as.” Understanding Formally vs Formerly helps you write clearer emails, reports, and messages. This distinction also strengthens reader comprehension and semantic precision in everyday and professional communication.
The Quick Difference Between Formally and Formerly
Use formally when you mean officially, properly, ceremonially, or according to established rules.
Use formerly when you mean previously, once, or in the past.
| Word | Main meaning | Root word | Common replacement | Example |
| Formally | In an official or proper manner | Formal | Officially | She was formally appointed as director. |
| Formerly | At an earlier time | Former | Previously | She was formerly the director. |
A quick question usually solves the problem:
- Are you describing how something happened? Use formally.
- Are you describing when something was true? Use formerly.
Why These Words Cause So Much Confusion
Both words are adverbs. Their spelling differs by only two letters in the middle, and many speakers pronounce them quickly. In normal conversation, the distinction can sound faint.
Consider this sentence:
The company was formally known as Westbridge Media.
The sentence is grammatically possible, yet it likely says the wrong thing. It suggests that Westbridge Media was the company’s official name. If the writer means the company had that name in the past, the correct wording is:
The company was formerly known as Westbridge Media.
That single letter changes the timeline.
How the Root Words Reveal the Meaning
The easiest way to separate the two words is to look inside them.
- Formal appears in formally.
- Former appears in formerly.
A formal action follows rules, customs, ceremony, or official procedure. A former role, name, or condition belongs to the past.
This root-word check works in nearly every situation. Before choosing a word, ask:
- Does the sentence relate to something formal?
- Does the sentence describe something former?
What Does “Formally” Mean?
Formally is an adverb that describes an official, proper, conventional, or ceremonial manner. It often modifies a verb and explains how an action happened.
Formally Meaning “Officially”
In business, law, education, and government, formally often means that someone completed an action through an accepted process.
Examples:
- The committee formally approved the budget.
- She formally accepted the position.
- The university formally announced the new policy.
- The attorney formally requested the records.
Formally Meaning “According to Rules”
- Employees must formally report safety concerns.
- The complaint was formally submitted in writing.
- Both parties formally agreed to the revised terms.
Here, formally emphasizes structure, documentation, or protocol.
Formally Meaning “In a Polite or Conventional Way”
Sometimes the word refers to appearance, speech, or behavior.
- The guests dressed formally for the banquet.
- He addressed the judge formally.
- They greeted each other formally before the meeting.
This use does not always involve law or authority. Instead, it describes a proper or traditional style.
Formally Meaning “Ceremonially”
Public events often use formally when an official performs a symbolic action.
- The mayor formally opened the new bridge.
- The president formally presented the award.
- The couple was formally introduced at the reception.
The action may carry social, institutional, or ceremonial importance.
How “Formally” Works in a Sentence
Writers usually place formally before the main verb or after a helping verb.
| Pattern | Example |
| Subject + formally + verb | The manager formally introduced the new employee. |
| Subject + helping verb + formally + past participle | The rule was formally adopted. |
| Verb + formally | Everyone dressed formally. |
| Formally + introductory phrase | Formally speaking, the agreement remains active. |
What “Formally” Does Not Mean
Formally does not mean previously. It cannot describe an old job, past name, earlier location, or prior condition.
Incorrect:
She was formally the sales manager.
Correct:
She was formerly the sales manager.
It also does not always mean politely. A person can speak politely without speaking formally. Friendly workplace language may be polite yet informal.
Finally, formally and officially overlap, but they are not perfect substitutes in every sentence. Officially often emphasizes recognized status. Formally may emphasize procedure, convention, or manner.
What Does “Formerly” Mean?
Formerly is an adverb of time. It means previously, once, or at an earlier point. Writers use it to connect a current identity or condition with a past one.
Examples:
- The theater was formerly a warehouse.
- She formerly worked in finance.
- The brand was formerly known as Northstar Goods.
- He is a consultant, formerly an attorney.
Every sentence points backward in time.
How “Formerly” Works in a Sentence
Writers often place formerly before the main verb, after a linking verb, or at the beginning of a descriptive phrase.
| Pattern | Example |
| Subject + formerly + verb | She formerly worked in publishing. |
| Subject + was/were + formerly + noun | The house was formerly a hotel. |
| Formerly + noun phrase | Formerly a warehouse, the building now contains offices. |
| Noun + formerly known as + name | The company, formerly known as Blue Peak, has rebranded. |
Be careful with awkward constructions.
Awkward:
He is formerly the company’s director.
Better:
He was formerly the company’s director.
Best in many contexts:
He is the company’s former director.
The revised sentences make the timeline clear.
“Formerly Known As” and “Formally Known As”
The phrase formerly known as means that a person, company, product, or place had a different name in the past.
The business, formerly known as Green Street Market, now operates as Harbor Foods.
By contrast, formally known as would mean “known by an official or formal name.” That meaning is possible, but the phrase is uncommon and often unclear.
Compare:
| Sentence | Meaning |
| The artist was formerly known as Luma. | The artist used the name Luma in the past. |
| The organization is formally known as the International Council for Coastal Research. | That is the organization’s official name. |
In most name-change situations, formerly known as is the correct phrase.
Side-by-Side Meaning Comparison
Here is the distinction in a compact form:
| Feature | Formally | Formerly |
| Main idea | Manner or procedure | Past time |
| Root | Formal | Former |
| Best replacement | Officially | Previously |
| Typical question | How did it happen? | When was it true? |
| Common context | Approval, ceremony, rules | Past role, name, use |
| Example | She formally resigned. | She formerly worked there. |
This is the heart of Formally vs Formerly: one word explains manner, while the other explains time.
“Formally” vs. “Officially”
These words often overlap, but they emphasize different ideas.
Officially focuses on recognized authority or status.
The school officially opened on August 15.
This sentence highlights the official opening date.
Formally can emphasize the ceremony or procedure.
The principal formally opened the school with a ribbon-cutting ceremony.
This sentence highlights how the opening happened.
Sometimes either word works:
- The board formally approved the plan.
- The board officially approved the plan.
However, the first version stresses procedure. The second stresses recognized approval.
“Formerly” vs. “Previously”
Both words refer to an earlier time, but they are not always equally natural.
Use formerly for an earlier identity, role, name, location, or condition.
- The office was formerly a bank.
- She was formerly the managing editor.
Use previously for an earlier action or event.
- She previously emailed the client.
- The team had previously rejected the proposal.
You can sometimes swap them, but tone and rhythm matter.
Less natural:
She formerly emailed the client.
More natural:
She previously emailed the client.
Common Mistakes and How to Correct Them
Using “Formally” for a Previous Name
Incorrect:
The hotel was formally known as The Carlton.
Correct:
The hotel was formerly known as The Carlton.
The hotel had that name in the past, so the sentence needs a time word.
Using “Formerly” for an Official Action
Incorrect:
The committee formerly approved the proposal.
Correct:
The committee formally approved the proposal.
The sentence describes the manner of approval, not an earlier time.
Assuming Context Will Fix the Error
Readers may understand your intention, but the wrong word can still damage clarity.
She was formerly introduced as the new president.
This sentence suggests someone introduced her that way in the past. If the introduction happened through an official process, write:
She was formally introduced as the new president.
Replacing “Officially” With “Formally” Every Time
Not every official fact is formal in manner.
The museum officially closed at 6:00 p.m.
This sentence states the recognized closing time. Formally closed would sound like a ceremonial or procedural shutdown.
Trusting Spellcheck Too Much
Spellcheck can identify a misspelled word. It may not identify a correctly spelled word used with the wrong meaning. Always test the sentence with a substitute:
- Replace formally with officially.
- Replace formerly with previously.
Case Study: Resume and Biography Writing
Word choice matters in professional profiles because readers expect a clear timeline.
Resume Example
Weak:
Formally served as marketing manager at Redwell Group.
Correct:
Formerly served as marketing manager at Redwell Group.
Stronger:
Served as marketing manager at Redwell Group from 2021 to 2024.
On a resume, dates often make formerly unnecessary. Direct wording usually sounds sharper.
Biography Example
Dana Lee is a communications consultant who formerly served as editor of City Review.
This sentence works because it contrasts Dana’s current role with a previous one.
Now compare:
Dana Lee was formally appointed editor of City Review in 2021.
Here, formally describes an official appointment.
The two words may appear in the same biography, but they perform different jobs.
Real-World Meaning Changes From One Letter
Both versions below are grammatical, yet they communicate different ideas.
The doctor was formally introduced as the department chair.
The introduction happened officially or ceremonially.
The doctor was formerly introduced as the department chair.
Someone introduced the doctor that way in the past, perhaps before the title changed.
Another pair:
The restaurant formally opened in May.
The restaurant held an official opening.
The restaurant formerly opened in May.
This suggests the restaurant used to open in May, which sounds incomplete or unusual.
Tiny spelling changes can produce large meaning changes. That is why context alone is not enough.
