How did the Roman invasion of Britain affect the English language?

The effect on the English language of the Roman invasion and occupation is negligible. Only around 200 Latin loanwords are inherited from the Romans - although by the 6th century the Church will have brought many more. Many of the Roman words are place names (London, Bath), or words coined by merchants and soldiers: win (wine), candel (candle), belt (belt), and weall (wall).
