Angela’s ‘special’ ABCs

This is a special post for my friend and neighbour, Paul-Enguerrand Fady (aged 15). He asks, following the posts on advice and advise, practice and practise, licence and license: ‘What is the difference between defence and defense?’ The answer is very simple: defence is the UK spelling while defense is the US spelling. The same goes for offence (UK spelling) and offense (US spelling).
