Bit of information lawyer's given by corporation (5)
I believe the answer is:
datum
'bit of information' is the definition.
'datum' can be an answer for 'bit' (I have seen 'Bit of dope' mean 'datum' so perhaps 'bit' could also mean 'datum'). I'm unsure of the 'of information' bit.
'lawyer's given by corporation' is the wordplay.
'lawyer' becomes 'da' (abbreviation for District Attorney).
'given' is a charade indicator (letters next to each other).
'by corporation' becomes 'tum' (I've seen this before. I am not sure about the 'by' bit.).
'da'+'tum'='DATUM'
Can you help me to learn more?
(Other definitions for datum that I've seen before include "Little bit of information" , "Fact or stat" , "Single informative fact" , "Fixed starting point for measurements" , "Single piece of information" .)
