Yes, “firstly” works as a transition word when it signals the first point in an ordered list, but “first” often reads cleaner.
If you’ve ever typed “firstly” and then paused, you’re not alone. Teachers, editors, and style guides don’t always react to it the same way. Some treat it as normal sequencing language. Others prefer “first” and reserve “firstly” for narrow cases.
This article clears up what “firstly” does, when it helps, when it sounds stiff, and what to use instead. Many ask, “is firstly a transition word?” You’ll get examples you can copy, plus quick checks to keep your paragraphs flowing without sounding forced.
Is Firstly A Transition Word? What the term means
A transition word or phrase signals how one idea connects to the next. It can show order (“first”), addition (“also”), contrast (“but”), cause (“so”), or time (“then”). “Firstly” sits in the “order” bucket: it tells your reader you’re starting a sequence.
So, yes: “firstly” is a transition word in the same way “first,” “secondly,” and “finally” are. The real question is whether it’s the best choice for your sentence and your audience.
Quick ways “firstly” gets used
Most uses of “firstly” fall into a few patterns. If your sentence matches one of these, you’re in safe territory.
| Situation | What “firstly” signals | Clean alternatives |
|---|---|---|
| Numbered points in an essay | Point 1 of 2+ points | first; to begin; to start |
| Formal letters and reports | Ordered list in a polite tone | first; first of all; to begin with |
| Meeting notes | Agenda order | first; item one; starting with |
| Step-by-step instructions | Step 1 in a process | first; step one; start by |
| Debate or argument writing | First reason in a chain | first; the first reason is |
| Speech scripts | Clear signposting for listeners | first; let’s start with |
| Academic papers with strict structure | Explicit sequencing | first; initially; to begin with |
| Short blog paragraphs | Often feels heavy for the space | first; start with; one reason |
What makes a word a transition in real writing
Transitions do two jobs at once. They point forward (“I’m about to add a new point”), and they point backward (“This new point fits the last one in a certain way”). “Firstly” mostly points forward. It’s a signpost that says, “We’re beginning the list.”
That’s why “firstly” often feels right when you have “secondly” and “thirdly” later. If you only have one point, or you switch to a different structure halfway through, “firstly” can feel like it’s waiting for a “secondly” that never arrives.
Does “firstly” need “secondly”?
It doesn’t need it by rule, but it tends to sound better when the list is clear. If you write “Firstly…” and then never give point two, the reader expects more structure than you deliver. In that case, swap to “first” or a sentence that names your main point without numbering it.
First vs. firstly: Why many writers pick “first”
“Firstly” is an adverb that means “in the first place.” Dictionaries treat it as standard English, and it’s been in use for centuries.
Still, many modern editors prefer “first” in most lists. That preference is about usage and tone, not a grammar error. Merriam-Webster notes a strong preference for “first” in list openings today, while still treating “firstly” as valid.
Where “firstly” can sound stiff
“Firstly” has a slightly formal, school-essay vibe. In tight writing, that extra syllable can feel like dead weight. It can also sound like you’re trying to prove you’re being formal. If your voice is casual, “first” usually blends in better.
A quick test: read the sentence out loud. If “firstly” makes you slow down, swap it. If it sounds natural, keep it.
Where “firstly” can help
“Firstly” can help when you truly want a “numbered” sound. In a speech, a training doc, or a structured report, that signposting can make the order feel clear. Cambridge Grammar notes in First, Firstly Or At First that both “first” and “firstly” can work for lists.
How to punctuate “firstly” without making a mess
Most of the time, “firstly” sits at the start of a sentence and is followed by a comma.
- Firstly, check the due date on the assignment sheet.
- Firstly, let’s set the terms so we’re using the same definition.
You can also drop it into the middle of a sentence, though that style is less common and can feel fussy.
- The plan is, firstly, to gather the sources and, secondly, to outline the argument.
If you’re writing for clarity, start-of-sentence is the cleaner move. It’s easier to scan, and it keeps your sentence from filling up with commas.
When “firstly” is the wrong tool
“Firstly” is not a magic fix for flow. It’s only a sequencing label. If your paragraph jumps topics, a numbered label won’t save it. Use “firstly” when you truly mean “this is point one,” not when you just want the paragraph to sound formal.
Single-point paragraphs
If you’re only making one point, skip “firstly.” Try a direct topic sentence instead.
- Weak: Firstly, schools should start later.
- Stronger: Schools should start later because teens’ sleep cycles run later.
Fake lists
A “fake list” is when you start with “firstly” but the next paragraphs aren’t numbered and don’t match the same structure. If you want that list feel, keep the pattern: first/second/third, or firstly/secondly/thirdly, and keep each point roughly parallel.
Better options than “firstly” for most student writing
If your goal is smooth, natural English, you often don’t need “firstly” at all. You can signal order with simpler words, or you can name the point in a strong topic sentence. In most essays, clarity beats fancy sequencing labels every time.
Simple order words
- First (short, flexible, works in formal and casual writing)
- Next (good when the order matters, not the count)
- Then (good for processes and timelines)
- Finally (best when you are truly wrapping the list)
Point-naming starters
These starters skip numbering and go straight to meaning. They often read stronger in essays.
- One reason is…
- The main issue is…
- A second point is…
- The last point is…
Process note: How this article chooses “best fit”
When deciding between “firstly” and an alternative, use two checks: (1) Are you truly listing 2+ points in order? (2) Does the tone match the audience? If the answer to either check is “no,” “first” or a point-naming starter is usually safer.
Transitions that do more than label order
Sometimes you want a transition that shows the relationship between ideas, not just the order. Purdue OWL explains on its page about writing transitions that they help readers connect sentences and paragraphs.
That’s why a plain “firstly” can feel thin in an argument paragraph. It tells the reader where they are in the list, but it doesn’t show how the claim links to the thesis. A tighter move is to name the logic.
Linking your point to the thesis
Try these patterns:
- First, this policy reduces costs by cutting waste.
- To start, the data shows a steady drop in errors after training.
- One reason this works is that it removes extra steps.
Notice what changes: the transition is still there, but the sentence carries meaning, not just order.
Is firstly a transition word in formal writing?
If your teacher asked, “is firstly a transition word?” the honest answer is yes. The better follow-up is which option fits the tone of your paragraph.
Yes, “firstly” can be a transition word in formal writing, and it shows up in reports, academic prose, and policy writing. Cambridge’s grammar notes that writers use “first” a lot, and that “first” and “firstly” both appear in lists.
Still, formal writing often rewards brevity. If your sentence already has long nouns and technical terms, “first” keeps the line lighter. Use “firstly” when the document uses a numbered style through the whole section, or when matching “secondly” feels natural.
Common mistakes with “firstly” and how to fix them
Mixing styles inside the same list
If you start with “firstly,” keep the same pattern for the rest of the list. Don’t switch to “second” or “last” unless you change the whole set.
- Off: Firstly… Second… Lastly…
- Clean: First… Second… Last…
- Clean: Firstly… Secondly… Lastly…
Using “firstly of all”
Some pairings don’t work in standard usage. Merriam-Webster points out that we don’t say “firstly of all.”
If you want that feel, use “first of all” or just “first.”
Hiding the real subject
A transition can’t replace a clear subject. If you write “Firstly, it is…” and the “it” has no clear noun, fix the noun first.
- Weak: Firstly, it is a problem when students are late.
- Clean: First, late arrivals break the first minutes of class.

Mini checklist before you keep “firstly”
Run these quick checks on your draft. They take ten seconds and prevent most “firstly” problems.
- Do you have two or more points? If not, drop the numbering.
- Do your points match in shape? Similar sentence patterns help readers scan.
- Do you keep the same style? Don’t mix first/firstly/initially in one set.
- Is the tone right for the reader? “Firstly” can sound formal; “first” fits more places.
- Does the transition carry meaning? If the topic sentence is weak, fix the topic sentence.
Takeaway: When to use “firstly” and when to skip it
“Firstly” is a real transition word. Use it when you’re clearly stepping through an ordered list and you plan to keep that list structure. If you want a lighter, more natural tone, “first” is often the smoother pick. When you want stronger writing, name your point right away and let the transition do less work.
