Tragedy of family meeting regal oddball (4,4)
I believe the answer is:
king lear
'tragedy' is the definition.
(I've seen this before)
'family meeting regal oddball' is the wordplay.
'family' becomes 'kin' (synonyms).
'meeting' says to put letters next to each other.
'oddball' indicates anagramming the letters.
'regal' anagrammed gives 'glear'.
'kin'+'glear'='KING LEAR'
'of' acts as a link.
(Other definitions for king lear that I've seen before include "Shakespearian royal tragedy" , "Tragic Shakespeare monarch" , "Play set in medieval Britain" , "Shakespearean tragedy" , "Tragic Shakespearean monarch" .)
