In what language is the motto of the English monarch written?

"Dieu et mon droit" (meaning "God and my right") is the motto of the Monarch of the United Kingdom outside Scotland. It appears on a scroll beneath the shield of the version of the coat of arms of the United Kingdom. The motto is said to have first been used by Richard I (1157–1199) as a battle cry and presumed to be a reference to his French ancestry and the divine right of the Monarch to govern. It was adopted as the royal motto of England by King Henry V (1386–1422) with the phrase "and my right" referring to his claim by descent to the French crown.

For the Royal coat of arms of the Kingdom of England to have a French rather than English motto was not unusual, given that Norman French was the primary language of the English Royal Court and ruling class following the rule of William the Conqueror of Normandy and later the Plantagenets.
