equerry
noun
[ ɪˈkwɛri ]
• an officer of the British royal household who attends or assists members of the royal family.
• "he became equerry to the Duke of Kent"
Origin:
early 16th century (formerly also as esquiry ): from Old French esquierie ‘company of squires, prince's stables’, from Old French esquier ‘esquire’, perhaps associated with Latin equus ‘horse’. The historical sense is apparently based on Old French esquier d'esquierie ‘squire of stables’.
