Ordinary man’s money — finally it’s found in pocket (4)
I believe the answer is:
joey
'pocket' is the definition.
Both the answer and definition are singular nouns.
Maybe there's an association between them I don't understand?
'ordinary man's money finally it's found in' is the wordplay.
'ordinary man' becomes 'jo' (I am not sure about the 'ordinary' bit.).
'finally' indicates one should take the final letters.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'found in' is an insertion indicator.
The final letter of 'money' is 'y'.
'jo'+'y'='joy'
'joy' placed around 'e' is 'JOEY'.
Can you help me to learn more?
(Other definitions for joey that I've seen before include "Threepenny bit" , "jumper, in a pocket?" , "Sydney's youngster" , "Baby boomer's" , "Young kangaroo" .)
