One maintaining uprightness in wild orgy (4)
I believe the answer is:
gyro
'one maintaining uprightness' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'wild orgy' is the wordplay.
'wild' indicates anagramming the letters.
'orgy' anagrammed gives 'GYRO'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for gyro that I've seen before include "Rotating device providing stability" , "Type of spinning compass" , "Stabilising device" , "Spin-stabilised device" , "Rotating stabiliser" .)
