Get out of bed to correct lie? (6)
I believe the answer is:
debunk
This might be a double definition.
'get out of bed' is the first definition.
(de-bunk could mean to get out of a bunk)
'correct lie?' is the second definition.
'debunk' can be an answer for 'correct' (thesaurus). I am not sure about the 'lie?' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for debunk that I've seen before include "Explode pretensions, myth, of" , "Expose pretensions of" , "Expose false claims" , "Show to be exaggerated or false, claim or theory" , "Show to be falsely honoured" .)
