Repeat manoeuvres involving variable circus equipment (7)
I believe the answer is:
trapeze
'circus equipment' is the definition.
'trapeze' can be an answer for 'equipment' (I have seen 'Acrobatic equipment ' mean 'trapeze' so perhaps 'equipment' could also mean 'trapeze'). I am not sure about the 'circus' bit.
'repeat manoeuvres involving variable' is the wordplay.
'manoeuvres' is an anagram indicator (letters manoeuvred in a new way).
'involving' is an insertion indicator.
'variable' becomes 'z' (algebra).
'repeat' is an anagram of 'trapee'.
'trapee' enclosing 'z' is 'TRAPEZE'.
Can you help me to learn more?
(Other definitions for trapeze that I've seen before include "Circus attraction" , "Horizontal bar as swing for acrobats" , "Acrobatic equipment" , "What the daring young man in the circus flies on" , "Apparatus for circus acrobats" .)
