Sluggard making little progress with a tutor (9)
I believe the answer is:
slowcoach
'sluggard' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'little progress with a tutor' is the wordplay.
'little progress' becomes 'slow' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'a tutor' becomes 'coach' ('coach' can be a synonym of 'tutor').
'slow'+'coach'='SLOWCOACH'
'making' acts as a link.
Can you help me to learn more?
(Other definitions for slowcoach that I've seen before include "Sluggish person like tardy trainer" , "certainly not one of the fleet" , "someone sluggish" , "One who's not very fast" , "Tortoise-like walker" .)
