Mixing up these two words is one of the most common mistakes in English writing because they look nearly identical on the page. Just one letter shifts the meaning from a tuxedo to a time machine. If you are describing a legal procedure or a fancy dinner, you need formally. If you are talking about history or an ex-job title, you need formerly.
Understanding the root words is the fastest way to solve this puzzle. One deals with form (structure/manners), and the other deals with former (the past).
What Does Formally Mean?
The word formally is an adverb that comes from the adjective “formal.” It relates to things done in accordance with rules, conventions, or etiquette. Think of it as doing something “properly” or “officially.”
Key Usage Scenarios
- Official Manner: When something is done legally or officially.
- Polite Behavior: Acting with strict manners or stiffness.
- Attire: Dressing in suits, gowns, or tuxedos.
When you do something formally, you are often following a protocol. For example, you don’t just ask a question; you formally submit a request. You don’t just wear clothes; you dress formally for a gala.
Examples in sentences:
- The contract has not yet been formally signed. (Official)
- Guests are requested to dress formally for the evening reception. (Clothing)
- She was formally introduced to the Queen. (Protocol)
What Does Formerly Mean?
Formerly is an adverb derived from “former.” It refers to time. It is a direct synonym for “previously” or “in the past.” If something has changed or no longer exists in its previous state, this is the word you want.
Memory Trick: Formerly refers to a Former time.
You will often see this word used when discussing geography (renamed cities), business (previous job titles), or history. It signals that the description is no longer true right now.
Examples in sentences:
- Istanbul was formerly known as Constantinople. (Past name)
- The building was formerly a bank, but now it is a library. (Past state)
- Formerly, we communicated via telegraph; now we use email. (Time period)

The “AL” vs “ER” Trick
If you are typing fast and get stuck, look at the middle letters of the word.
Formerly
Contains ER.
Think: Earlier.
Common Mistakes to Avoid
Writers often confuse these two when the sentence structure allows for an adverb but the context is tricky. Always ask yourself: Am I talking about how something is done (Style/Law) or when something happened (Time)?
❌ Incorrect: “He was formally the director of marketing.”
Why it’s wrong: This sentence implies he was the director in a “formal manner” (wearing a tuxedo while directing?), rather than saying he held the job in the past.
✅ Correct: “He was formerly the director of marketing.”
❌ Incorrect: “The accused was formerly charged with theft.”
Why it’s wrong: Unless the charges were dropped and belong to the past, this is incorrect. You likely mean the legal process has officially happened.
✅ Correct: “The accused was formally charged with theft.”
Quick Summary
Using the right word builds authority. If you are discussing official business, legal matters, or high-end dress codes, keep it formal. If you are discussing history, ex-partners, or old job titles, leave it in the former times.
- Formally = Officially / Elegantly.
- Formerly = Previously / In the past.
