Does it ease the map-maker's problems? (6)
I believe the answer is:
relief
'it ease the map-maker's problems?' is the definition.
The definition suggests a singular noun which matches the answer.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for relief that I've seen before include "Alleviation of anxiety" , "Assistance given to people in need" , "Lightening of a burden" , "Help or easement" , "Deliverance from siege" .)
