Carry out service, son, embraced by diplomacy (8)
I believe the answer is:
transact
'carry out' is the definition.
(I've seen this before)
'service son embraced by diplomacy' is the wordplay.
'service' becomes 'ran' (I can't explain this - if you can you should give a lot more credence to this answer).
'son' becomes 's' (genealogical abbreviation for son).
'embraced by' is an insertion indicator.
'diplomacy' becomes 'tact' (tact can mean diplomacy or sensitivity).
'ran'+'s'='rans'
'rans' put within 'tact' is 'TRANSACT'.
Can you help me to learn more?
(Other definitions for transact that I've seen before include "Conduct business, negotiate" , "Perform or carry out business" , "handle" , "Carry out, like business" , "Conduct trade" .)
