Are like regions or districts (5)
I believe the answer is:
areas
'districts' is the definition.
(I've seen this in another clue)
'are like regions' is the wordplay.
I cannot quite see how this works, but
an anagram of 'are' is 'rea' which is located in the answer.
'like' could be 'as' and 'as' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for areas that I've seen before include "Localities" , "Places" , "Zones" , "Spaces covered by two-dimensional surfaces" , "Geographical regions" .)
