Both “practising” and “practicing” are correct. The spelling you need depends entirely on which English variety you are writing in, not on grammar rules or personal preference. This guide breaks down the exact difference, when to use each form, and how to stay consistent across your writing.

Practising or Practicing – Quick Answer

Practising is the British English spelling of the present participle (the “-ing” form) of the verb practise. Practicing is the American English spelling of the same word. Both mean the same thing: repeating an activity to improve a skill or carrying out a profession.

The rule is simple. If your audience reads UK-style English, use practising. If your audience reads US-style English, use practicing.

The Origin of Practising or Practicing

The word traces back to the Greek term praktikos, meaning fit for action. It passed through Latin and Old French before entering English as practise and practice. English spelling split into two paths over time.

British English kept the older “-ise” and “-ising” pattern for the verb form, giving practise and practising. American English simplified the spelling so that practice covers both the noun and the verb, including its “-ing” form, practicing. This split mirrors other British-American spelling differences such as organise versus organize and colour versus color.

British English vs American English Spelling

The split between practising and practicing fits a wider pattern in British versus American spelling.

Notice that the noun form, practice, stays the same in both varieties. Only the verb and its “-ing” form change spelling in British English.

Which Spelling Should You Use?

Choose based on your audience, not your personal habit.

• Use practising if you are writing for UK, Indian, Pakistani, Australian, or Commonwealth readers.
• Use practicing if you are writing for American readers or publishing on a US-based platform.
• For global or mixed audiences, pick one style guide and apply it consistently throughout the entire piece.

Most style guides, including those used by major publishers and universities, expect you to commit to one regional spelling system and avoid mixing British and American forms in the same document.

Practising or Practicing Meaning

Both spellings carry the same meaning. As a present participle, the word describes:

• Repeating an activity regularly to build or improve a skill, such as practising the guitar.
• Actively working in a profession, such as a lawyer practising law or a doctor practicing medicine.
• Following a custom, habit, or belief, such as practising a religion.

The meaning never changes between the two spellings. Only the regional convention does.

4. They are _____ for the championship match.
5. He keeps _____ until the routine feels natural.

Practising or Practicing Grammar & UK Rules

In British English, the spelling depends on the word’s grammatical role, not just the “-ing” ending.

• Practise (verb): I practise the violin daily.
• Practising (verb, -ing form): She is practising the violin.
• Practice (noun): Daily practice improves your skill.

The rule holds even for compound terms. Best practice and best practices always use the “c” spelling because practice is functioning as a noun, never as a verb, in that phrase. This is one of the most commonly searched grammar questions tied to this word, since writers often assume the “s” spelling applies anywhere the word is used as a verb-like form.

Practising or Practicing in a Sentence

Practising or Practicing in Everyday Examples

The word shows up constantly outside formal writing too.

• Sports: The team has been practising drills since early morning.
• Music: She is practicing scales before her recital.
• Religion: His family has been practising their faith for generations.
• Workplace: New hires spend the first week practising company procedures.

Practising or Practicing Law / Certificate / Doctor

This is where the spelling matters most for professional and legal writing.

• A practising lawyer (UK) is the same as a practicing lawyer (US). Both describe someone actively licensed and working in law.
• A practising certificate is the standard British English term for the document that authorizes a solicitor to work. In American English, this would typically be called a practice certificate or license, since “practicing certificate” is rarely used as a fixed term.
• A practising doctor (UK) and a practicing doctor (US) both refer to a physician currently treating patients, as opposed to one who is retired or working outside clinical medicine.

Always match the spelling to the country whose legal or medical system you are referencing. A UK law firm’s website should use practising; a US hospital’s website should use practicing.

Practising or Practicing – Google Trends & Usage Data

Search and usage data consistently show a clear regional pattern. Practicing dominates search volume overall, largely because American English has the largest base of English content and searchers online. Practising remains the steady, standard choice across the UK, India, Pakistan, Australia, and most Commonwealth countries, where it appears consistently in news, education, and government writing.

For content creators, this means the better-performing spelling is not about which one is “more popular” worldwide. It is about matching the spelling to where your specific readers are searching from. A site targeting Indian or UK readers should default to practising even though practicing has higher global search numbers.
