US lawyer with corporation provides statistic (5)
I believe the answer is:
datum
'statistic' is the definition.
(I've seen this in another clue)
'us lawyer with corporation' is the wordplay.
'us lawyer' becomes 'DA' (abbreviation for District Attorney).
'with' says to put letters next to each other.
'corporation' becomes 'tum' (I've seen this before).
'da'+'tum'='DATUM'
'provides' is the link.
(Other definitions for datum that I've seen before include "Given item" , "bit of info" , "Fixed starting point for measurements" , "Single piece of information" , "Minimal information" .)
