Father and son put on payroll in Bow (4)
I believe the answer is:
sire
'father' is the definition.
(synonyms)
'son put on payroll in bow' is the wordplay.
'son' becomes 's'.
'put on payroll in bow' becomes 'ire' (I can't explain this - if you can you should give a lot more credence to this answer).
's'+'ire'='SIRE'
'and' is the link.
Can you help me to learn more?
(Other definitions for sire that I've seen before include "Rise for male parent (4)." , "Make children" , "Stallion; beget" , "Male parent of, say, horse" , "Male parent of an animal" .)
