Manoeuvre in pool, backwards, repeated around article (4-3-4)
I believe the answer is:
loop-the-loop
'manoeuvre' is the definition.
(I have seen 'Aerobatic manoeuvre ' mean 'loop-the-loop' so perhaps 'manoeuvre' could also mean 'loop-the-loop')
'pool backwards repeated around article' is the wordplay.
'backwards' is a reversal indicator.
'repeated' indicates the doubling of some letters.
'around' means one lot of letters goes inside another.
'article' becomes 'the' (the definite article in English).
'pool' reversed gives 'loop'.
'loop' doubled is 'looploop'.
'looploop' placed around 'the' is 'LOOP-THE-LOOP'.
'in' is the link.
(Other definitions for loop-the-loop that I've seen before include "Aerobatic manoeuvre" , "Fly a vertical circle" .)
