Livewires quite a few backed in parties (7)
I believe the answer is:
dynamos
'livewires' is the definition.
I can't tell whether this defines the answer.
'quite a few backed in parties' is the wordplay.
'quite a few' becomes 'many' (I've seen this in another clue).
'backed' shows that the letters should be reversed in order.
'in' indicates putting letters inside.
'parties' becomes 'dos' (do is a kind of party).
'many' back-to-front is 'ynam'.
'ynam' inserted into 'dos' is 'DYNAMOS'.
Can you help me to learn more?
(Other definitions for dynamos that I've seen before include "Electricity generators or energetic people" , "Electricity producers" , "highly energetic people" .)
