Ceremony in honour of African country, stuffing knocked out of Turkey! (9)
I believe the answer is:
formality
'ceremony' is the definition.
(I know that formality is a type of ceremony)
'honour of african country stuffing knocked out of turkey' is the wordplay.
'honour of' becomes 'for' (I can't justify this - if you can you should give a lot more credence to this answer).
'african country' becomes 'mali' (country in Africa).
'stuffing knocked out of' says to hollow out the word (remove centre letters) (the letters which stuff into the word are removed).
'turkey' with its middle taken out is 'ty'.
'for'+'mali'+'ty'='FORMALITY'
'in' is the link.
Can you help me to learn more?
(Other definitions for formality that I've seen before include "ceremony" , "Social rigidity" , "Established convention" , "Stiffness" .)
