Indolent, lazy (6)
I believe the answer is:
otiose
I believe this is a double definition.
'indolent' is the first definition.
(I know that indolent can be written as otiose)
'lazy' is the second definition.
(I know that lazy can be written as otiose)
(Other definitions for otiose that I've seen before include "Serving no useful purpose" , "Disinclined to work or exert oneself" , "Devoid of worth or significance" , "Serving no good purpose" , "Without practical purpose" .)
