A simple way to remember it:
- If your audience is global or American → use synchronize
- If your audience is British or Commonwealth → use synchronise
Why Synchronize Is Preferred in American English
American English follows a more standardized spelling system that favors simplicity and consistency. One major rule is the preference for the suffix “-ize” instead of “-ise.”
American English Spelling Pattern
Examples include:
- organize (UK: organise)
- realize (UK: realise)
- customize (UK: customise)
- synchronize (UK: synchronise)
This pattern makes American English more uniform across technical and academic writing.
Webster’s Dictionary Influence
Noah Webster played a major role in shaping American spelling. His goal was to simplify English spelling and make it more logical.
He promoted:
- Simplified word endings
- Consistent spelling rules
- Reduced French-influenced variations
Because of this influence, synchronize became the standard in the United States.
Modern Usage in Technology and Business
Today, American spelling dominates in:
- Software interfaces
- Mobile apps
- Cloud storage systems
- Programming documentation
- International business tools
For example, Apple and Google both use “sync” and “synchronize” in American spelling formats in global products.
Why Synchronise Is Used in British English
British English retains older spelling traditions influenced by Latin and French language patterns. That is why it often uses “-ise” endings.
British English Spelling Style
Examples include:
- organise
- realise
- analyse
- synchronise
This structure is deeply rooted in historical language development.
Historical Language Influence
British English absorbed many French spelling conventions during medieval times. French often used “-ise” endings, which influenced English spelling in the UK.
As a result, British English preserved:
- More traditional spellings
- Less standardized simplification
- Greater variation across words
Modern British Usage
Even today, institutions in the UK prefer:
- synchronise
- organise
- recognise
However, both forms may appear depending on publication style guides.
