Legend of empty mystery and truth (4)
I believe the answer is:
myth
'legend' is the definition.
(I've seen this before)
'empty mystery and truth' is the wordplay.
'empty' suggests removing the centre.
'and' is a charade indicator (letters next to each other).
'truth' becomes 'th' (I can't justify this - if you can you should believe this answer much more).
'mystery' with its centre removed is 'my'.
'my'+'th'='MYTH'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for myth that I've seen before include "Story of old gods" , "Fanciful story" , "lie!" , "Widely held misconception" , "false interpretation?" .)
