If you have ever stopped while typing a message or an essay to wonder whether you should write practising or practicing, you are definitely not alone. This is one of the most common spelling dilemmas in the English language, and it causes confusion for students, professionals, and native English speakers alike.
The reason these two spellings look so similar is that they represent a major regional difference between British English and American English. In this article, you will learn the exact rules behind both spellings, which one you should use, and how to never mix them up again.
Whether you use practising or practicing depends entirely on whether you are writing in British English or American English. In British, Australian, and Canadian English, practising with an “s” is the standard spelling for the verb form.
In American English, practicing with a “c” is used for both the verb and the adjective. For example, a British writer would say, “She is practising the piano,” while an American writer would say, “She is practicing the piano.”
Which One Should You Use?
Choosing between these two spellings comes down to your target audience or regional style guide. If you are writing for an American audience, or if your school or workplace follows American publishing standards, you should always use practicing. If you live in the United Kingdom, Australia, New Zealand, South Africa, or follow British spelling conventions, practising with an “s” is the correct choice for the verb.
Keep in mind that this rule only applies to the verb form (doing an activity to get better) and the adjective form (a practising lawyer). In American English, the noun is always spelled practice with a “c”, while in British English, the noun is practice and the verb is practise.
The most important takeaway is to pick one regional standard and stick to it consistently throughout your entire document.

Meaning of Word 1: Practising
Definition and Grammar Role
The spelling practising functions as the present participle and gerund of the verb practise. In British and Commonwealth English, verbs that end in -ise often keep that spelling when changed into continuous tenses.
Common Uses and Everyday Situations
You use this spelling when someone is actively engaging in an activity to improve their proficiency, or when describing someone who actively follows a religion or profession.
- Natural Example: She spends two hours every afternoon practising yoga.
- Natural Example: He is a practising attorney in London.
Meaning of Word 2: Practicing
Definition and Grammar Role
The spelling practicing functions as the present participle and gerund of the verb practice. American English simplifies many spelling rules, using the letter “c” for both the noun and the verb forms.
Where It Is Used and Why
This form is standard across the United States and is increasingly common in global business writing due to the widespread influence of American software, media, and education standards.
- Natural Example: The basketball team is practicing free throws after school.
- Natural Example: Are you practicing your speech for the conference tomorrow?
Why Do People Confuse These Words?
The confusion between these two words exists because both are technically correct depending on geographic location, yet spellcheckers often flag one as an error depending on your computer’s language settings. Writers frequently switch back and forth without realizing it, leading to inconsistent documents. Understanding that this is merely a transatlantic spelling variation clears up the mystery instantly.
Grammar Rule
The underlying rule involves how British and American English handle words with dual noun-verb spellings. In British English, the noun is spelled with a “c” (practice) and the verb is spelled with an “s” (practise). When you turn the British verb practise into a continuous form, it becomes practising. In American English, practice serves as both the noun and the verb, so adding -ing simply attaches to the end, resulting in practicing.
| Region | Noun Spelling | Verb Spelling | Continuous Verb Form |
| British English | Practice | Practise | Practising |
| American English | Practice | Practice | Practicing |

Easy Memory Trick
To easily remember which is which, look at the letters inside the words. Practising contains the letter S, which can stand for Seaside or Singapore (common in Commonwealth regions that use British English). Practicing contains the letter C, which can stand for Capitol or Chicago (representing American English). Alternatively, remember that British uses S (practising), while American uses C (practicing).

Frequently Asked Questions (FAQs)
Is one spelling considered more correct than the other?
Neither spelling is universally superior; correctness depends entirely on whether you are using British English or American English standards.
Can “practising” be used as a noun?
No. Both practising and practicing are verb forms. The noun form in both American and British English is always spelled practice.
Why does British English change the spelling for verbs?
British English often uses -ise endings for verbs (such as organise or realise) while keeping -ice for nouns, which extends to the distinction between practise and practice.
Which spelling should I use for international communication?
American spelling (practicing) is generally accepted worldwide in digital spaces, but consistency within your specific document is always the highest priority.
Do spellcheckers flag these words as errors?
Most word processors will flag a spelling as an error if it conflicts with the dictionary region (US vs. UK) set in your document preferences.
Are there other words with this same spelling pattern?
Yes, similar pairs include licence (noun) and license (verb) in British English, though American English uses license for both.
Conclusion
Mastering the difference between practising and practicing comes down to recognizing regional writing standards. While practising with an “s” serves British and Commonwealth writers well, practicing with a “c” dominates American English and global digital communication.
The simplest rule to remember is: Use “practicing” for American audiences, and “practising” for British audiences. Keep your spelling consistent throughout your text, and you will never need to second-guess your writing choice again.
