Asterisk in English: Rules, Uses, and Examples

Asterisk punctuation refers to the small star-shaped symbol (*), which directs readers to notes, marks corrections, hides letters, or labels unusual language forms. Although it looks simple, its meaning changes according to where and how it appears.

The word asterisk comes from a Greek word meaning “little star.” In everyday English, the symbol is common in books, academic papers, advertisements, online messages, dictionaries, and linguistic studies.

Referring to Footnotes

An asterisk can connect information in the main text with a footnote at the bottom of the page.

Example:

Registration is free for children under twelve.*

*Proof of age may be required.

The first asterisk tells readers that additional information appears elsewhere on the page.

Asterisks work best when a document contains only a small number of notes:

• Use one asterisk for the first note: *
• Use two asterisks for a second note: **
• Use numbered footnotes when several notes are needed.
• Keep the symbol close to the sentence or word it explains.
• Follow the same placement style throughout the document.

Text	Note
The offer ends on Friday.*	*The closing date may vary by location.
Students receive a 20% discount.*	*A valid student card is required.
Delivery is available nationwide.*	*Some remote areas are excluded.

Numbered references are usually easier to follow in research papers, reports, and longer documents.

Marking Additional Information

An asterisk may introduce a condition, exception, warning, or qualification connected to a statement.

All rooms include free breakfast.*

*Breakfast is not included on public holidays.

This use is common in:

• Advertisements
• Product descriptions
• Price lists
• Application forms
• Event announcements
• Terms and conditions

The additional note should be clear and easy to find. An asterisk should not be used to hide an important restriction in tiny or confusing text.

Main Statement and Added Condition

Main text	Additional information
Free delivery on all orders.*	*Minimum order value applies.
The course is available online.*	*Live classes are offered in selected regions.
Members can cancel anytime.*	*Outstanding payments must be cleared first.

The note may be grammatically complete or written as a short phrase, depending on the document style.

Correcting Words in Informal Writing

In chats, comments, and text messages, an asterisk can show that the writer is correcting a mistake.

I will meet you on Firday.
*Friday

The corrected word is often written in a new message with an asterisk before it.

Another common style places the symbol after the correction:

Friday*

Both forms are understood in informal communication, but placing the asterisk before the corrected word is often clearer.

Correcting More Than One Word

A longer correction may include the full corrected phrase:

She have completed the work.
*She has completed the work.

Use this method only in casual writing. In formal emails, reports, and academic work, rewrite the sentence correctly instead of adding an asterisk.

Hiding Letters in Sensitive Words

Asterisks sometimes replace letters in profanity, insults, or other sensitive terms.

What the h*** happened?

He used a d*** offensive expression.

This style allows readers to recognise the intended word without showing every letter.

Asterisks may also protect private information:

• Email: m****@example.com
• Phone number: 0300-*******
• Account number: **** 7842
• Personal name: A**** Khan

The symbol does not always make information fully private. Readers may still guess a hidden word from its context, length, or visible letters.

For accessible writing, avoid replacing too many letters when the exact word is necessary for understanding, reporting, or education.

Asterisks in Linguistics

In linguistics, an asterisk before a word, phrase, or sentence usually shows that the form is grammatically unacceptable.

*She go to school every day.

The asterisk indicates that the sentence does not follow standard English grammar. The correct version is:

She goes to school every day.

Another example:

*He explained me the problem.

Correct forms include:

He explained the problem to me.

He explained the problem.

The symbol does not mean that the sentence is false. It means that the structure is considered grammatically unacceptable in the variety of English being analysed.

Common Linguistic Symbols

Symbol	Meaning	Example
*	Grammatically unacceptable	*She are ready.
?	Questionable or unnatural	?She gave the book John.
✓	Acceptable form	She is ready.
#	Grammatically possible but unsuitable in context	#The stone drank some tea.

Linguistic judgements may depend on dialect, context, and meaning. A form marked unacceptable in standard written English may still appear in a regional dialect or informal speech.

Placement with Other Punctuation

The position of an asterisk depends on its purpose and the chosen style guide.

Footnote Asterisks

When an asterisk refers to a footnote, many style guides place it after the punctuation mark:

The results were unexpected.*

Only registered members may enter.*

When the note applies to one specific word, the symbol may appear directly after that word:

The basic* package does not include technical support.

*“Basic” refers to the monthly starter plan.

Linguistic Asterisks

In linguistics, place the asterisk before the unacceptable form:

*They was waiting outside.

Do not place it at the end of the sentence because it must immediately signal the grammatical judgement.

Informal Corrections

The symbol usually appears beside the corrected word:

*necessary

necessary*

The first style is often easier to recognise as a correction.

Purpose	Usual placement	Example
Footnote reference	After the relevant text or punctuation	The fee is refundable.*
Specific word note	Immediately after the word	Premium* users
Grammar judgement	Before the sentence or form	*He don’t agree.
Informal correction	Before or after the corrected word	receive / receive
Hidden letters	Inside the word	s***d
Private information	In place of hidden characters	A**** Khan

Because publishers use different conventions, check the required style guide before preparing formal work.

');win.document.close();} if(p.mode==='hub'){state.title=p.title||'Punctuation Practice Centre';renderHub('');}else{begin(p.topic,p.title,p.questions,p.articleUrl,p.articleTitle);}} onReady(function(){document.querySelectorAll('.vbpq2-wrap').forEach(init);}); })();

Common Errors

1. Using too many asterisks:
   Several symbols make a page difficult to read. Use numbered notes for longer documents.
2. Forgetting the matching note:
   Every footnote asterisk should lead to clear additional information.
3. Separating the symbol from its word:
   Do not insert an unnecessary space between a word and its asterisk.
   Incorrect: Offer *Correct: Offer*
4. Placing linguistic asterisks at the end:
   In grammar analysis, the symbol belongs before the unacceptable form.
   Incorrect: She have a car.
*Correct: *She have a car.
5. Using corrections in formal writing:
   Rewrite the error rather than adding a correction symbol in professional documents.
6. Hiding important conditions:
   An asterisk should clarify an offer, not conceal a major fee, restriction, or obligation.
7. Mixing placement styles:
   Choose one convention and use it consistently.
8. Confusing an asterisk with a multiplication sign:
   An asterisk may represent multiplication in computing, but the mathematical multiplication symbol is ×.

FAQs About Asterisk

Short Summary

The asterisk (*) has several practical roles in English. It can direct readers to footnotes, add conditions, correct informal mistakes, hide letters, and mark unacceptable forms in linguistics. Its placement changes with its purpose, so writers should apply one clear style consistently.
