Empire (5)

I believe the answer is:

'empire' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for realm that I've seen before include "Royal domain" , "Kingdom; field of interest" , "Kingdom, domain" , "King's domain" , "Area of interest/activity" .)

I've seen this clue in the Penny Press, The Mirror and the King Feature Syndicate.
