Smoother compliment (7)
I believe the answer is:
flatter
This could be a double definition.
'smoother' is the first definition.
Both the definition and answer are comparative adjectives. Perhaps there's a link between them I don't understand?
'compliment' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for flatter that I've seen before include "more lifeless" , "Offer insincere compliments, butter up" , "Over-praise" , "drier" , "Fawn, blandish" .)
