Reporter beginning to judge yours and my denial (6)
I believe the answer is:
journo
'reporter' is the definition.
'beginning to judge yours and my denial' is the wordplay.
'beginning to' indicates taking the first letters.
'yours and my' becomes 'our' (I've seen this before).
'denial' becomes 'no' (no is a kind of denial).
The first letter of 'judge' is 'j'.
'j'+'our'+'no'='JOURNO'
(Other definitions for journo that I've seen before include "Newspaper writer, colloquially" , "Hack" , "sub?" , "Newspaper employee (slang)" .)
