Spaces are as a result! (5)
I believe the answer is:
areas
'spaces' is the definition.
(I've seen this in another clue)
'are as a result' is the wordplay.
I cannot really understand how this works, but
an anagram of 'are' is 'rea' which is present in the answer.
'as' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for areas that I've seen before include "Geographical regions" , "Places" , "Zones" , "Localities" , "Spaces covered by two-dimensional surfaces" .)
