This information is just a little backward (4)
I believe the answer is:
data
'this information is' is the definition.
'data' can be an answer for 'information' (data are bits of information). I am not certain of the rest of the definition.
'a little backward' is the wordplay.
'little' becomes 'tad' (both can mean a small amount).
'backward' is a reversal indicator.
'a'+'tad'='atad'
'atad' written backwards gives 'DATA'.
'just' is the link.
Can you help me to learn more?
(Other definitions for data that I've seen before include "intelligence" , "computer input?" , "Input; facts" , "Listed facts" , "Contents of some banks?" .)
