first of all (first)

'First of all' is grammatically correct but often wordy. In many written contexts you can tighten a sentence by using 'first', deleting the phrase, or choosing a stronger transition.

Below are concise rules, clear rewrite patterns, and many ready-to-copy examples for work, school, and casual writing so you can fix sentences immediately.

Quick answer

Prefer 'first' for concise, formal lists; drop the phrase when the sequence is obvious; keep 'first of all' only for conversational emphasis.

'First' is shorter and clearer in formal writing.
Omit any introductory marker if the ordering is already clear.
Use 'first of all' for spoken or friendly tones, or for rhetorical emphasis.

Core explanation: why 'first of all' often feels heavy

'First of all' is a multi-word discourse marker. 'First' performs the same job with fewer words, which improves clarity and pace. When a sentence already implies order, the marker adds noise.

Decide by function: clarify order (use 'First' or numbers), give an instruction (drop the marker), or add emphasis (keep 'first of all').

Formal lists: use 'First,' not 'First of all.'
Instructions: usually drop the marker and use an imperative.
Conversational or emphatic tone: 'First of all' is acceptable.

Wrong: First of all, we should review the numbers before we decide.
Right: First, we should review the numbers before deciding.

Grammar: what 'first' and 'first of all' do (and punctuation)

'First' functions as an adverbial or ordinal; 'first of all' is an adverbial phrase used as a discourse marker. Both often appear at the sentence start and take a comma when followed by an independent clause.

Use a comma after 'First' or 'First of all' when the phrase introduces a full clause. Very short clauses sometimes omit the comma, but keep punctuation consistent across a document.

Correct: 'First, update the dataset.'
Also correct (conversational): 'First of all, thanks for your help.'
Avoid inconsistent punctuation: don't alternate 'First' with 'First of all' across similar sentences.

Right: First, update the dataset.
Wrong: First of all we need to check the schedule. (missing comma)
Right: First of all, we need to check the schedule.

Spacing & small formatting tips

After 'First' or 'First of all' use a single comma when introducing an independent clause. Avoid extra commas or unusual spacing.

If the introductory phrase is very short and followed by a short clause, some writers omit the comma for speed-but prefer clarity and be consistent.

Correct: 'First, we will gather the data.'
Incorrect: 'First of all we will gather the data' (missing comma).
Incorrect: 'First, of all, we...' (double comma; redundant).

Wrong: First, of all, thank you for coming.
Right: First of all, thank you for coming.

Hyphenation: don't try to hyphenate the phrase

Do not hyphenate 'first of all.' Hyphens belong in compound adjectives (for example, 'first-rate'), not in discourse markers.

If you're tempted to hyphenate because you want an adjective, rewrite. Replace 'first-of-all approach' with 'initial approach' or 'first priority.'

'First of all' - no hyphens, three words.
If you need an adjective, use 'initial', 'primary', or 'first' with a noun.
Avoid inventing hyphenated forms to force a grammatical role the phrase doesn't fit.

Usage: Incorrect: a first-of-all reminder. Better: an initial reminder or the first reminder.

Real usage and tone: when 'first of all' fits

Use 'first of all' for warm, spoken, or emphatic tones: podcasts, speeches, friendly emails, and texts. For formal emails, reports, and essays, choose 'first' or drop the marker.

For formal documents with several points, prefer 'First,' 'Second,' or numbered headings instead of 'First of all.'

Work (formal): Prefer 'First,' or numbered lists.
School (academic): Use 'First,' or omit; avoid conversational markers in essays.
Casual (friends, social): 'First of all' works for emphasis or friendliness.

Casual: First of all, congrats on the move! - fine in a text.
Work: First, we will analyze Q1 sales and report back. - better in a memo.
School: First, the study shows a correlation between X and Y. - preferred in essays.

Try your own sentence

Check the whole sentence rather than the phrase by itself: the surrounding words usually show whether the marker is needed.

A quick memory trick (two questions) to stop overusing it

Ask these two quick questions when you type 'first of all': (1) Is a sequence needed? (2) Do I want a conversational tone? If the answer is 'no' to the first, delete it. If 'no' to the second, replace with 'first' or omit it.

Practice by scanning a recent email or paragraph, finding up to three instances of 'first of all', and applying the test. Small edits quickly reduce overuse.

Two-question test: sequence? tone?
Edit three past sentences this week to build the habit.
Prefer 'first' in formal prose; keep 'first of all' for speech or friendly writing.

Usage: Original: 'First of all, I'll say thank you.' → Edit: 'I'll say thank you.'

Similar mistakes to watch for

Other transition phrases can be overused or sound conversational. Audit them the same way you audit 'first of all'.

Don't stack lead-ins; choose one clear marker or use numbered points.

Watch: 'first and foremost', 'to begin with', 'in the first place', 'last but not least'.
Avoid stacking: don't write 'First of all, secondly...'.
In formal documents, prefer numbered lists ('1.', '2.') instead of many lead-in phrases.

Wrong: First of all, and most importantly, we must increase revenue.
Right: Our top priority is increasing revenue.
