An error in the wage packet? (7)
I believe the answer is:
payslip
'an error in' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'wage packet?' is the wordplay.
'wage' becomes 'pay' (synonyms).
'packet?' becomes 'slip' (I can't justify this - if you can you should give a lot more credence to this answer).
'pay'+'slip'='PAYSLIP'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for payslip that I've seen before include "Detachable form accompanying cheque" , "Piece of paper accompanying remittance" , "Capital of Italy" , "Paper to accompany cheque" , "Record of wages earned" .)
