Label whale starting from the rear flipper? (7)
I believe the answer is:
acrobat
'flipper?' is the definition.
(I've seen this in another clue)
'label whale starting from the rear' is the wordplay.
'label' becomes 'tab' (I've seen this before).
'whale starting' becomes 'orca' (I can't explain this - if you can you should give a lot more credence to this answer).
'from the rear' is a reversal indicator.
'tab'+'orca'='taborca'
'taborca' back-to-front is 'ACROBAT'.
Can you help me to learn more?
(Other definitions for acrobat that I've seen before include "circus artiste" , "Performer going head over heels?" , "User of five ac" , "Gymnastic performer" , "flipper" .)
