Tackle part to support graduate's performance (9)
I believe the answer is:
rigmarole
'performance' is the definition.
(I've seen this before)
'tackle part to support graduate's' is the wordplay.
'tackle' becomes 'rig' (I've seen this in other clues).
'part' becomes 'role' (eg a theatrical role).
'to' says to put letters next to each other (I've seen this in other clues).
'support graduate' becomes 'ma' (I can't explain this - if you can you should give a lot more credence to this answer).
'role' after 'ma' is 'marole'.
'rig'+'marole'='RIGMAROLE'
Can you help me to learn more?
(Other definitions for rigmarole that I've seen before include "red tape?" , "garbled nonsense" , "A grim role for long rambling statement" , "boring series" , "Performance" .)
