Avoided showing a noted figure to be dead wrong (6)
I believe the answer is:
evaded
'avoided' is the definition.
(evading is a kind of avoiding)
'a noted figure to be dead wrong' is the wordplay.
'a noted figure' becomes 'ev' (I can't explain this - if you can you should give a lot more credence to this answer).
'to' says to put letters next to each other.
'wrong' indicates an anagram.
'dead' anagrammed gives 'aded'.
'ev'+'aded'='EVADED'
'showing' is the link.
Can you help me to learn more?
(Other definitions for evaded that I've seen before include "Avoided, dodged" , "Sidestepped" , "avoided answering" , "'Dodged, eluded (6)'" , "Escaped or avoided" .)
