It's telling it like it is to a Cork member of the clergy (8)
I believe the answer is:
accurate
'it's telling it like it is' is the definition.
(I've seen this before)
'a cork member of the clergy' is the wordplay.
'cork' becomes 'c' (this could be a standard abbreviation of which I'm unaware).
'member of the clergy' becomes 'curate' (I've seen this before).
'a'+'c'+'curate'='ACCURATE'
'to' is the link.
Can you help me to learn more?
(Other definitions for accurate that I've seen before include "Precise, correct" , "not deviating from the truth?" , "Spot-on" , "telling it like it is" , "Precise and exact (8)" .)
