Are like regions or zones (5)
I believe the answer is:
areas
'zones' is the definition.
(I've seen this before)
'are like regions' is the wordplay.
I cannot really understand how this works, but
an anagram of 'are' is 'rea' which is within the answer.
'like' could be 'as' and 'as' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'or' is the link.
Can you help me to learn more?
(Other definitions for areas that I've seen before include "Spaces covered by two-dimensional surfaces" , "Localities" , "Geographical regions" , "Places" , "Zones" .)
