Formally vs. Formerly – Which is Correct?

The distinction between formally and formerly is crucial for clear communication, as these adverbs, despite their similar sound, have entirely different meanings. Formally relates to adhering to rules, customs, or official procedures. Formerly, on the other hand, refers to something that happened or existed in the past, indicating a previous state or time.

Formally or Formerly – Which is Correct?

Both formally and formerly are correct English words, but they are not interchangeable. Their core difference lies in their function: formally is an adverb of manner, describing how something is done (in a formal or official way), while formerly is an adverb of time, describing when something occurred (in the past, previously).

The Best Trick to Remember the Difference

A simple trick to distinguish them is to focus on their root words. Formally contains the word “form,” which can remind you of rules, structure, or official conduct. Think “following the form.” Formerly contains “former,” which directly means “previous” or “past.” If you can substitute “previously” into your sentence, then “formerly” is likely the correct choice. If you can substitute “officially” or “in a proper manner,” then “formally” is what you need.

Word	Part of Speech	Meaning	Example
Formally	Adverb	In a formal or official manner; according to strict rules or etiquette.	The president formally addressed the nation.
Formerly	Adverb	In the past; previously.	She was formerly the director of marketing.

How to Use Formally

The adverb formally describes an action performed in a way that adheres to established rules, customs, or official protocols. It can also refer to something done with a serious, dignified, or ceremonial tone. When something is done formally, it implies a certain level of respect, seriousness, or official recognition. It often contrasts with casual or informal approaches.

Example 1: The company decided to formally announce the merger at a press conference.

Example 2: Guests were asked to dress formally for the gala dinner.

Example 3: He formally apologized for his outburst during the meeting.

Etymology of the word Formally

The word “formally” derives from the Old French “formal” (meaning “pertaining to form or rule”) and the Latin “formalis” (from “forma,” meaning “form, shape, beauty”). The suffix “-ly” transforms the adjective “formal” into an adverb, indicating “in a formal manner.” Its usage has consistently related to adherence to form, rules, or official status since its emergence in English around the 15th century.

How to Use Formerly

The adverb formerly indicates a past state, position, or condition that is no longer current. It points to something that existed or occurred at an earlier time. It is used to contrast a present situation with a previous one, often implying a change has taken place. It functions as an adverb of time, much like “previously” or “in the past.”

Example 1: The building, formerly a library, is now a community center.

Example 2: Dr. Anya Sharma, formerly a researcher at CERN, joined our team last year.

Example 3: The city council formerly met on Tuesdays, but now convenes on Wednesdays.

Etymology of the word Formerly

“Formerly” comes from the Old French “former” (meaning “preceding, earlier”) and ultimately from the Latin “forma,” but in this context, it emphasizes the idea of something being “before” or “prior.” The English adjective “former” means “previous” or “earlier in time.” Adding the adverbial suffix “-ly” creates “formerly,” meaning “in a former time; previously.” This usage became common in English from the late 14th century.
