Mean to give information (3-4)
I believe the answer is:
low-down
I believe this is a double definition.
'mean' is the first definition.
(I've seen this before)
'information' is the second definition.
(I know that low-down is a type of details)
'to give' acts as a link.
(Other definitions for low-down that I've seen before include "Mean, unfair" , "Data - base" , "Info (slang) - dishonourable" , "Inside story" , "Inside information - mean (7;3-4)" .)
