Chap I make better, giving treatment for nails (8)
I believe the answer is:
manicure
'treatment for nails' is the definition.
I can't judge whether this definition defines the answer.
'chap i make better' is the wordplay.
'chap' becomes 'man' (I've seen this before).
'make better' becomes 'cure' (I've seen this before**).
'man'+'i'+'cure'='MANICURE'
'giving' acts as a link.
Can you help me to learn more?
(Other definitions for manicure that I've seen before include "Grooming for 10, 17 and 18" , "Hand and nail treatment" , "Professional hand treatment" , "Work on nails" , "Hands/nails treatment" .)
