Constantine initially leads half-hearted online community to information on IMDB (6)
I believe the answer is:
credit
'constantine initially leads half-hearted online community' is the definition.
I can't judge whether this defines the answer.
'information on imdb' is the wordplay.
I cannot quite see how this works, but
'information' could be 'i' (common abbreviation for information) and 'i' is present in the answer.
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found within the answer.
The remaining letters 'cdt' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for credit that I've seen before include "it's on the cards?" , "Due recognition for kind of loan?" , "Believe - recognition" , "Praise; tick" , "Add (money) to account" .)
