Stronger and less slovenly (6)
I believe the answer is:
neater
This might be a double definition.
'stronger' is the first definition.
Both the answer and definition are comparative adjectives. Maybe you can see an association between them that I can't see?
'less slovenly' is the second definition.
(I've seen this in another clue)
'and' is the link.
Can you help me to learn more?
(Other definitions for neater that I've seen before include "More tidy and orderly" , "More spick and span" , "straighter" , "Tidier" , "More tidy and uncluttered" .)
