### Clue: Pages confuse the royal way of being "up" (10)
### Answer: SIDESADDLE 
 ### Explanation: Definition: the royal way of being "up" 
**SIDES** ("pages") + **ADDLE** ("confuse") 
*Not an equestrian, but I thought sidesaddle referred to a way that a woman used to ride a horse, rather than a royal personage?
