Have you ever typed “defence or defense” and paused before finishing your sentence? You are not alone. This is one of the most common British and American English spelling differences.
Both defence and defense are correct spellings. The main difference is where the spelling is used.
Defence is the standard spelling in British English and is also common in other varieties influenced by British English, including Australian English and Indian English.
Defense is the standard American English spelling.
This difference can appear in school assignments, news articles, sports, military writing, business documents, legal writing, websites, and everyday conversations. It can also be confusing because both words have exactly the same meaning and almost the same pronunciation.
For example, an American newspaper might write, “The team improved its defense,” while a British newspaper may write, “The team improved its defence.”
Neither sentence is wrong. The spelling simply follows a different English convention.

The Origin of Defence or Defense
The word comes through Old French and ultimately traces back to the Latin defendere, meaning to protect or ward off.
English adopted the word with spelling influenced by French.
Over time, English developed different spelling traditions. British English generally retained -ce in the noun defence, while American English standardized the noun as defense.
This difference is part of a much larger pattern in English spelling.
For example:
| British English | American English |
|---|---|
| defence | defense |
| offence | offense |
| licence | license* |
| pretence | pretense |
*The word licence/license has an additional grammar distinction in British English, so it is not exactly the same situation as defence/defense.
The spelling difference became more noticeable as American English developed its own conventions.
How to Pronounce Defence or Defense
The two spellings are normally pronounced the same way.
A simple pronunciation is:
defence → dih-FENS
defense → dih-FENS
The word has two syllables:
de-fence
The final sound is similar to “fens.”
Easy Speaking Trick
Think:
de + fence
The second part sounds like fence.
Do not pronounce the ending as “fens-ee” or add another syllable.
Pronunciation Tip
Both British and American speakers generally pronounce the noun with stress on the second syllable:
de-FENCE

| Academic writing | defence | defense | Follow local style |
| Formal writing | defence | defense | Both correct |
