Some moaned aloud over being charged (5)
I believe the answer is:
laden
'being charged' is the definition.
(I've seen this before)
'some moaned aloud over' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'over' says the letters should be written backwards.
'nedal' can be found hidden inside 'moaned aloud'.
'nedal' back-to-front is 'LADEN'.
(Other definitions for laden that I've seen before include "Of ship, having taken on cargo" , "Carrying a load" , "Loaded with cargo or burden" , "Carrying goods" , "Eland (anag)" .)
