How Defence Is Used
The word defence is used in many contexts, including:

Origin of Defence
The spelling defence comes from Middle English and Old French, which heavily influenced British English. Over time, British English retained the “-ce” ending in words like:
- Defence
- Licence
- Offence
In summary:
Defence = British English spelling for protection, security, or resistance.

This spelling is standard in:

- Offence → Offense
In summary:
Defense = American English spelling for the same concept of protection or resistance.
