Swinger's nude antics, getting covered in fruit (8)
I believe the answer is:
pendulum
'swinger's' is the definition.
(I've seen this before)
'nude antics getting covered in fruit' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'nude' is 'endu' which is located in the answer.
'fruit' could be 'plum' (plum is a kind of fruit) and 'plum' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pendulum that I've seen before include "It swings to and fro as in old clock" , "Old time swinger?" , "Lead swinging" , "Oscillating mechanism" , "Nude lump (anag)" .)
