Individual to furnish information in different ways (9)
I believe the answer is:
singleton
'individual' is the definition.
(someone who is single)
'to furnish information in different ways' is the wordplay.
'to furnish information' becomes 'sing' (sing can mean to confess).
'in different ways' becomes 'leton' (I can't justify this - if you can you should give a lot more credence to this answer).
'sing'+'leton'='SINGLETON'
(Other definitions for singleton that I've seen before include "lonely heart, perhaps" , "in club, maybe, all alone" , "Eg lonely heart" , "Stolen gin (anag.)" , "Bachelor maybe" .)
