Neighbourhood call about nothing unusual (5)
I believe the answer is:
local
'neighbourhood' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'call about nothing unusual' is the wordplay.
'about' means one lot of letters go next to another.
'nothing' becomes 'O' (looks like zero - 0).
'unusual' indicates an anagram.
'call' after 'o' is 'ocall'.
'ocall' with letters rearranged gives 'LOCAL'.
Can you help me to learn more?
(Other definitions for local that I've seen before include "Confined to a place" , "stopping train" , "Village inn" , "In nearby area" , "Hostelry" .)
