Cite to a doctor you see reported September second (6)
I believe the answer is:
adduce
'cite' is the definition.
(I know that cite can be written as adduce)
'a doctor you see reported september second' is the wordplay.
'doctor' becomes 'DD' (Doctor of Divinity).
'you' becomes 'u' (homophones).
'see reported september second' becomes 'ce' (I can't justify this - if you can you should give a lot more credence to this answer).
'a'+'dd'+'u'+'ce'='ADDUCE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for adduce that I've seen before include "Cite in support" , "Allege" , "Cue dad (anag)" , "Bring up in discussion" , "Cite as evidence" .)
