Eminence of pound dropping one place in range (8)
I believe the answer is:
altitude
'eminence' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for altitude that I've seen before include "Elevation above sea-level" , "Angular distance above the horizon" , "Lofty position" , "Elevation above sea level" , "Height (above ground)" .)
