You're very good at solving this, for example? (10)
I believe the answer is:
compliment
This might be a double definition.
'you're very good at solving this' is the first definition.
The definition suggests a singular noun which matches the answer.
'example?' is the second definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'for' is the link.
Can you help me to learn more?
(Other definitions for compliment that I've seen before include "Politely congratulate" , "tribute" , "Word of praise" , "Commend, flatter" , "Expression of polite admiration" .)
