Lie about nothing when in charge (6)
I believe the answer is:
lounge
'lie' is the definition.
(thesaurus)
'about nothing when in charge' is the wordplay.
'about nothing' becomes 'o' (looks like zero - 0. I am not sure about the 'about' bit.).
'when in' is an insertion indicator.
'charge' becomes 'lunge' (I've seen this in another clue).
'o' inserted inside 'lunge' is 'LOUNGE'.
Can you help me to learn more?
(Other definitions for lounge that I've seen before include "Living room" , "Loll, sit about idly" , "Parlour" , "Waste time -- glue on (anag)" , "Sit idly in comfortable room" .)
