Grooming hard worker to take time for run (6)
I believe the answer is:
toilet
'grooming hard worker' is the definition.
'toilet' can be an answer for 'grooming' (both can mean a personal cleaning routine). I'm unsure of the 'hard worker' bit.
'to take time for run' is the wordplay.
'take' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'for' means one lot of letters go next to another (I've seen this in other clues).
'run' becomes 'ile' (I am not sure about this - if you are sure you should believe this answer much more).
't' put after 'ile' is 'ilet'.
'to' next to 'ilet' is 'TOILET'.
(Other definitions for toilet that I've seen before include "Lavatory paper" , "something to go on?" , "Plumbing fixture" , "A formal loo" , "Waste disposal unit" .)
