Answer:
'Roi' is the french word for 'king' and as the intellect of individuals differs it is conceivable that the intellect of a particular French king may fall below the demarcation of idiocy. However when discussing such things it is often advisable that you do not accuse any French king of idiocy within the ken of any French royalists as this may instigate arguments and fisticuffs. As you have not done this and you spelled idiot incorrectly in the first place one might consider it justifiable to apply the term to you.
