Practises and practices are both correct English words, but they are not always used in the same way. The difference mainly depends on grammar and regional spelling conventions.
In British English, practises is the third-person singular form of the verb practise, while practices is usually the plural form of the noun practice. In American English, however, practice is used as both a noun and a verb, so its third-person singular form is practices.
This small spelling difference can cause confusion in emails, academic writing, professional documents, websites, and everyday communication. Choosing the right form becomes much easier once you know whether the word is being used as a noun or a verb and which variety of English you are writing in.
In this guide, you will learn the difference between practises and practices, their meanings, British and American usage, common mistakes, practical examples, and simple rules for choosing the correct form.
Quick Answer
The answer depends on grammar and regional English.
- Practises is a verb used mainly in British English.
- Practices is a plural noun in both British and American English.
- Practices is also the verb form used in American English.
- In British English, the verb is spelled practise, and its third-person singular form is practises.

Compare these examples:
| Sentence | Correct? | Why? |
|---|---|---|
| She practises the piano every day. | ✅ British English | Practises is a verb. |
| She practices the piano every day. | ✅ American English | Practices is the American verb. |
| Doctors follow strict practices. | ✅ British & American | Practices is a plural noun. |
| The company has several business practices. | ✅ British & American | Practices is a plural noun. |
| He practises medicine. | ✅ British English | Practises is a verb. |
| He practices medicine. | ✅ American English | Practices is a verb. |
The easiest rule is:
British English: practise = verb, practice = noun.
American English: practice = both verb and noun.
What Does “Practises” Mean?
Practises is the third-person singular form of the verb practise in British English.
It means that someone regularly performs an activity to improve a skill, prepare for something, or develop ability. It can also describe someone who works professionally in a particular field.
For example:
- She practises the piano every evening.
- He practises his speech before the presentation.
- The athlete practises for several hours each day.
- She practises law in London.
- The doctor practises medicine at a local hospital.
Here, practises describes an action performed by he, she, or it.
The related forms are:
- practise — base verb
- practises — third-person singular
- practising — present participle
- practised — past tense and past participle
For example:
She practises her pronunciation every morning.
She practised her pronunciation yesterday.
She is practising her pronunciation now.
This spelling system is standard in British English and is also followed by several other varieties of English influenced by British usage.
What Does “Practices” Mean?
Practices has more than one grammatical use.
In British English, practices is normally the plural form of the noun practice.
For example:
- Good business practices build customer trust.
- Different cultures have different religious practices.
- The hospital introduced new safety practices.
- These teaching practices help students learn more effectively.
In American English, practices can also be the third-person singular form of the verb practice.
For example:
- She practices the piano every day.
- He practices law in New York.
- The team practices every afternoon.
- Maria practices her presentation before the meeting.
Therefore, practices is not automatically wrong in British English. The important point is that British English normally uses practise as the verb, whereas American English uses practice as both noun and verb.
Practise vs Practice: The Main Difference
The easiest way to understand the issue is to separate the noun from the verb.
In British English
British English generally follows this distinction:
- practice = noun
- practise = verb
Examples:
Regular practice improves your skills.
Here, practice is a noun.
She practises the piano every day.
Here, practises is a verb.
In American English
American English normally uses practice for both grammatical roles.
Examples:
Regular practice improves your skills.
Here, practice is a noun.
She practices the piano every day.
Here, practices is a verb.
This is why British and American writers may spell the same sentence differently.
British English vs American English
The distinction becomes particularly important when writing for a specific audience.
| Meaning | British English | American English |
|---|---|---|
| Base verb | practise | practice |
| Third-person verb | practises | practices |
| Present participle | practising | practicing |
| Past tense | practised | practiced |
| Noun | practice | practice |
| Plural noun | practices | practices |
Consider this sentence:
British English:
Sarah practises her presentation every morning.
American English:
Sarah practices her presentation every morning.
Both sentences are correct. The difference is regional spelling.
However, this sentence remains the same in both varieties:
Sarah has several good practices for preparing presentations.
Here, practices is a plural noun, so both British and American English use the same spelling.
Why Does British English Use “Practise” and American English Use “Practice”?
The difference comes from the development of English spelling conventions.
The noun practice and verb practise developed as related forms, and British English eventually maintained a spelling distinction between the two. The -ice ending became associated with the noun, while -ise became associated with the verb.
This pattern can be seen in British English with several related word pairs, although not every word follows exactly the same rule.
American English took a different approach and generally standardized practice for both the noun and verb. As a result, American writers do not normally need to distinguish between practice and practise based on grammatical function.
The difference is therefore not about one spelling being more correct than the other. It is mainly a matter of regional English conventions.
When Should You Use “Practises”?
Use practises when:
- You are writing in British English.
- The word is functioning as a verb.
- The subject is singular and third person, such as he, she, or it.
Examples:
- She practises yoga every morning.
- He practises his presentation before meetings.
- The musician practises for two hours each day.
- My brother practises the guitar after school.
- The lawyer practises criminal law.
- The doctor practises medicine in Manchester.
Notice that the spelling changes when the subject changes:
I practise every day.
You practise every day.
They practise every day.
She practises every day.
The -s ending is added because the subject is third-person singular.
When Should You Use “Practices”?
Use practices in two main situations.
1. As a plural noun
This use is standard in both British and American English.
Examples:
- Modern teaching practices have changed.
- The company follows ethical business practices.
- Traditional cultural practices vary between regions.
- The school introduced new safety practices.
- These farming practices protect the soil.
Here, practices refers to multiple methods, habits, procedures, or ways of doing something.
2. As a verb in American English
American English uses practices as the third-person singular form of the verb practice.
Examples:
- She practices the piano every evening.
- He practices law in Chicago.
- The team practices before every game.
- The student practices speaking English every day.
In British English, these would normally use practises instead.
“Practises or Practices” in Real-World Writing
The difference can appear in many types of writing. Understanding the context makes the correct choice easier.
In Emails
British English:
James practises his presentation before every client meeting.
American English:
James practices his presentation before every client meeting.
If you are writing a professional email to a UK audience, practises is the natural choice for the verb.
In Academic Writing
British English:
The researcher examines how teachers practise inclusive education.
American English:
The researcher examines how teachers practice inclusive education.
However:
The study compares different teaching practices.
Here, practices is a plural noun in both varieties.
In Business Writing
Business writing often uses practices as a noun:
The company has adopted more sustainable business practices.
This spelling is correct in both British and American English.
But if you use the word as a verb:
British:
The company practises responsible management.
American:
The company practices responsible management.
In Websites and Blogs
A British website might say:
Learn how to practise better writing habits.
An American website might say:
Learn how to practice better writing habits.
But a heading such as:
Best Writing Practices
uses practices because it refers to multiple methods or approaches.
In Everyday Conversation
The same regional distinction applies in everyday English.
British:
She practises speaking English every day.
American:
She practices speaking English every day.
The pronunciation is essentially the same, so the difference is mainly visible in writing.
Common Mistakes With Practises and Practices
Several mistakes occur because learners hear these words more often than they see them in writing.
Mistake 1: Using “practices” as a British verb
A common mistake is:
❌ She practices the piano every day.
If you are following standard British English spelling, write:
✅ She practises the piano every day.
The word is a verb, so British English uses practise.
Mistake 2: Assuming “practises” is always wrong
This is also incorrect.
❌ “Practises” is not an English word.
It is a valid word in British English.
For example:
She practises her pronunciation every morning.
That sentence is perfectly correct in British English.
Mistake 3: Confusing the noun with the verb
Consider:
The company follows good business practices.
Here, practices is a noun.
But:
The company practises ethical management.
Here, practises is a verb in British English.
The easiest test is to ask:
Is the word naming a method, habit, or procedure?
If yes, it is probably the noun practice/practices.
Is it describing an action someone performs?
If yes, it is probably the verb practise/practises in British English.
Mistake 4: Mixing regional spelling systems
Avoid switching between British and American forms in the same piece of formal writing.
For example:
She practises every morning and the program is optimized for students.
This may mix British and American conventions depending on the rest of the document.
A consistent style is usually better.
A Simple Trick to Remember the Difference
A useful memory trick for British English is:
Practice is a noun; practise is an action.
You can associate the c in practice with a concept or thing.
You can associate the s in practise with an action.
For American English, the rule is simpler:
Practice is both the noun and the verb.
So if you are writing for an American audience, you do not need to worry about choosing between practise and practice for the verb.
Practice or Practise in “Fitness to Practice”
The phrase fitness to practise is particularly common in British English, especially in professional and regulatory contexts.
For example:
The board reviewed the doctor’s fitness to practise.
Here, practise is a verb.
In American English, the equivalent is generally:
The board reviewed the doctor’s fitness to practice.
Therefore:
| British English | American English |
|---|---|
| fitness to practise | fitness to practice |
| right to practise medicine | right to practice medicine |
| licence to practise | license to practice |
The exact wording can vary by profession and jurisdiction, but the spelling follows the broader British/American distinction.
“Best Practices” or “Best Practises”?
The correct phrase is:
Best practices
This is true in both British and American English when practices is being used as a plural noun.
For example:
The guide explains the best practices for online security.
Teachers should follow best practices when creating accessible lessons.
The company developed new best practices for customer service.
Best practises would not normally be correct when you mean multiple recommended methods.
This is an important distinction because the word may look like the British verb practises, but in best practices, it is a plural noun.
“Practice” or “Practise” in Professional Fields
The spelling can also depend on whether you are talking about an activity or a professional field.
Medical field
British English:
She practises medicine.
American English:
She practices medicine.
But the noun remains:
She works at a medical practice.
And:
Several medical practices operate in the area.
Legal field
British English:
He practises commercial law.
American English:
He practices commercial law.
As a noun:
He joined a law practice.
Several law practices attended the conference.
This distinction shows why context matters more than the appearance of the word.
More Examples of Practises and Practices
Here are examples covering common situations:
British English
- She practises the violin every evening.
- He practises speaking French with his friends.
- The doctor practises medicine in Bristol.
- She practises mindfulness before bed.
- The student practises difficult vocabulary.
- Good study practices can improve performance.
- The school changed its teaching practices.
- The company follows ethical business practices.
American English
- She practices the violin every evening.
- He practices speaking French with his friends.
- The doctor practices medicine in Boston.
- She practices mindfulness before bed.
- The student practices difficult vocabulary.
- Good study practices can improve performance.
- The school changed its teaching practices.
- The company follows ethical business practices.
Notice that the difference appears mainly when practice/practise is functioning as a verb. The plural noun practices is spelled the same in both varieties.
Related Word Forms
Knowing the other forms can help you avoid similar mistakes.
| Form | British English | American English |
|---|---|---|
| Base verb | practise | practice |
| Third-person singular | practises | practices |
| -ing form | practising | practicing |
| Past tense | practised | practiced |
| Noun | practice | practice |
| Plural noun | practices | practices |
Examples:
British:
She practises every day.
She is practising now.
She practised yesterday.
American:

She is practicing now.
She practiced yesterday.
These forms follow the same basic spelling distinction.
Which Spelling Should You Use?
Choose the spelling based on your target audience.
Use British English if:
- Your readers are mainly in the UK.
- You are following British academic conventions.
- Your organization uses British English.
- You are writing for a British publication.
- You want consistency with other British spellings.
Use:
practise → practises → practising → practised
Use American English if:
- Your audience is mainly in the United States.
- Your organization follows American English.
- You are writing for an American publication.
- Your style guide specifies US English.
Use:
practice → practices → practicing → practiced
What about international audiences?
For an international website, either variety can work. The most important thing is consistency.
If your website generally uses British spellings such as colour, organise, centre, and travelling, then practise/practises will usually fit that style.
If your website uses color, organize, center, and traveling, then practice/practices will normally fit the American style.
Consistency helps readers understand that the spelling differences are intentional rather than accidental.
How to Choose the Correct Word
When you see practises or practices, follow these steps:
Step 1: Identify the grammar.
Ask whether the word is a noun or a verb.
Step 2: Check whether it is singular or plural.
If it is a plural noun, practices is correct.
Step 3: Identify your English variety.
For British English, use practise as the verb.
For American English, use practice as the verb.
Step 4: Check the subject.
In British English:
I practise.
She practises.
In American English:
I practice.
She practices.
This simple process eliminates most errors.
