Lids seen flickering -- condition of one slouching? (8)
I believe the answer is:
idleness
'condition of one slouching?' is the definition.
(slouch can mean to be lazy or idle)
'lids seen flickering' is the wordplay.
'flickering' indicates anagramming the letters (I've seen this in other clues).
'lids'+'seen'='lidsseen'
'lidsseen' anagrammed gives 'IDLENESS'.
(Other definitions for idleness that I've seen before include "Laziness" , "Sloth - there may be love in it" , "Send lies (anag.)" , "State of doing nothing" , "Disinclination to work" .)
