Terrible apartheid shown in chart (3,6)
I believe the answer is:
hit parade
'in chart' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'terrible apartheid' is the wordplay.
'terrible' indicates anagramming the letters.
'apartheid' anagrammed gives 'HIT PARADE'.
'shown' acts as a link.
Can you help me to learn more?
(Other definitions for hit parade that I've seen before include "Those once charting" , "Pop charts" , "Selling CDs" , "list of winners" , "Top-selling numbers" .)
