riddle

'puzzle' is the definition.
(riddling is a kind of puzzling)

'might be draining' is the wordplay.
'might' becomes 'ridd' (I am not sure about this - if you are sure you should believe this answer much more).
'be' becomes 'lie' (lying is a kind of being).
'draining' suggests removing the centre (I've seen 'drained' mean this).
'lie' with its centre removed is 'le'.
'ridd'+'le'='RIDDLE'

'that' acts as a link.

Can you help me to learn more?
