The French 'gu' (that you hear in 'segue') was pronounced as 'w' in Norman. So 'guerre' phonetically is close to 'guer', 'wer', 'war'. There is a lot of fun words like this.

Also, there is French legalese that went into English, like 'cancellation' that gave 'cancel' in English, and now sound very English for French people.

There are plenty of g/w examples still present wholly within English, too -- guarantee and warranty is the one I usually point to.

Likewise, Guillaume and William are the same name. (And if you're into medieval lit, Gawain and Wawain.)
