Faze means to disturb or upset someone, while phase means a stage or period in a process.
Have you ever written a sentence and wondered whether faze or phase is the right word? You are not alone. These two words sound the same, which makes them easy to confuse. However, they have different meanings and should not be used in the same situations.
People often search for faze or phase because both words are pronounced /feɪz/, but their meanings are completely different. Faze is a verb that means to disturb, worry, upset, or unsettle someone. Phase usually means a stage or period in a process. It can also be used as a verb in phrases such as phase in and phase out. Cambridge defines faze as upsetting or worrying someone, while phase refers to a stage or period that forms part of a longer process.
This guide explains the difference between faze or phase in simple language. You will learn their meanings, origins, common mistakes, British and American usage, everyday examples, and practical rules for choosing the correct word.

The Origin of Faze or Phase
The origin of faze
The verb faze appeared in American English around 1830. Etymological records connect it with the older dialect word feeze, meaning to frighten, alarm, or discomfit. Its deeper history can be traced to Old English forms meaning to drive away or put to flight.
Over time, faze developed its modern meaning of disturbing or unsettling someone.
For example:
The difficult question did not faze the student.
The related word unfazed means not disturbed or worried. It has been recorded since the early 20th century.
The origin of phase
Phase has a completely different history. It entered English in the early 18th century in connection with the changing appearance of the moon. The word came through Modern Latin from Greek phasis, meaning appearance.
Its meaning later expanded from the appearance of the moon to a particular stage or period of development.
For example:
The company is entering a new phase of growth.
The word phase is now common in science, business, education, technology, and everyday English.
Why do faze and phase cause confusion?
The main reason is pronunciation. Faze and phase are pronounced the same way in both British and American English. Cambridge gives the pronunciation of faze as /feɪz/ in both varieties.
They are therefore homophones, meaning they sound alike but have different spellings and meanings.
British English vs American English Spelling
Is there a British and American spelling difference?
No. Faze and phase are not British and American spelling variations.
Both British and American English use:
| Word | British English | American English | Meaning | Example |
|---|---|---|---|---|
| Faze | Faze | Faze | To disturb or upset | The news did not faze her. |
| Fazed | Fazed | Fazed | Disturbed or upset | He was not fazed by the criticism. |
| Phase | Phase | Phase | A stage or period | The project entered a new phase. |
| Phased | Phased | Phased | Done in stages | The changes were phased in. |
So, unlike colour and color or centre and center, you do not choose faze or phase based on whether you are writing for a British or American audience.
The meaning determines the spelling.
How are the words used in both varieties?
British and American writers use faze when referring to someone’s emotional reaction.
The pressure did not faze the player.
Both varieties also use phase for stages and periods.
The project has reached its final phase.
The basic distinction remains the same in both forms of English.
Which Spelling Should You Use?
American English
Use faze when something does not bother or unsettle a person.
Public speaking does not faze her.
Use phase for a stage or period.
The company is entering a new phase.
British English
The same rule applies in British English.
The criticism did not faze him.
The project is in its second phase.
There is no regional spelling choice between these two words.
UK and Commonwealth Countries
Writers in the UK and Commonwealth countries should also choose the word according to its meaning.
Do not assume that faze is an American spelling of phase. They are separate words with different histories.
International Readers
For international writing, use the word that matches your intended meaning.
If you mean disturb, choose faze.
If you mean stage, choose phase.
This simple rule works regardless of the reader’s country.
Academic and Professional Writing
Be especially careful with these words in formal writing. A spelling mistake can change the meaning of your sentence.
For example:
The criticism did not faze the researcher.
This means the researcher was not disturbed.
But:
The criticism did not phase the researcher.
This does not express the intended meaning.
