One of Shakespeare's tragedies (4,4)
I believe the answer is:
king lear
'one of shakespeare's tragedies' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for king lear that I've seen before include "drama" , "One of Shakespeare's tragedies" , "Part of ruler" , "Shakespearean tragedy" , "Tragic hero" .)
