Manages successfully to get fluctuations in (6)
I believe the answer is:
swings
'manages' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Maybe there's a link between them I don't understand?
'successfully to get fluctuations in' is the wordplay.
I cannot really understand how this works, but
'get' could be 'win' (winning is a kind of getting) and 'win' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for swings that I've seen before include "Moves in a curve" , "What you lose on these, you'll gain on the roundabouts" , "What you lose on these, you hopefully gain on the roundabouts" , "Pieces of playground equipment" , "Sways" .)
