Expecting to relinquish power for ruling (7)

Ross

I believe the answer is:

regnant

I'm a little stuck... Click here to teach me more about this clue!

'for ruling' is the definition.
(as in a queen regnant, a queen who rules by birth)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for regnant that I've seen before include "Ruling" , "(Queen) in her own right" , "Current" , "exercising authority" , "Reigning" .)

I've seen this clue in The Hindu.
