Repulsed supporter restraining rowing instructor making missile (6)
I believe the answer is:
exocet
'missile' is the definition.
(I've seen this before)
'repulsed supporter restraining rowing instructor' is the wordplay.
'repulsed' says the letters should be written in reverse.
'supporter' becomes 'tee' (a golf tee acts as a support).
'restraining' indicates putting letters inside.
'rowing instructor' becomes 'cox' (I can't justify this - if you can you should believe this answer much more).
'tee' going around 'cox' is 'tecoxe'.
'tecoxe' reversed gives 'EXOCET'.
'making' acts as a link.
Can you help me to learn more?
(Other definitions for exocet that I've seen before include "Tactical missile" , "Short range guided missile" , "French anti-ship guided missile" , "French missile used by Argentina in the Falklands War" , "Type of guided missile" .)
