Cope with an extract from myth and legend (6)
I believe the answer is:
handle
'cope with' is the definition.
(I've seen this before)
'an extract from myth and legend' is the wordplay.
'an extract from' indicates the answer is hidden within the clue (some letters extracted from the clue).
'HANDLE' is hidden in the letters of 'myth and legend'.
(Other definitions for handle that I've seen before include "Part by which something is carried" , "Manage - touch - hilt" , "Person's name (slang)" , "Part by which something is held" , "Manage - name" .)
