Little data found in certain forms (4)
I believe the answer is:
info
'little data' is the definition.
'info' can be an answer for 'data' (I've seen this before). I'm not certain of the 'little' bit.
'in certain forms' is the wordplay.
'in' says the answer is hidden in the clue.
'INFO' can be found hidden inside 'certain forms'.
'found' is the link.
Can you help me to learn more?
(Other definitions for info that I've seen before include "Knowledge (colloq.)" , "News" , "counsel?" , "Dope" , "What's known" .)
