Wooden seat features Black Sea port (6)
I believe the answer is:
odense
'black sea port' is the definition.
'odense' can be an answer for 'port' (I've seen this before). I am unsure of the 'black sea' bit.
'wooden seat features' is the wordplay.
'features' indicates the answer is hidden within the clue (I've seen 'featuring' mean this).
'ODENSE' can be found hidden inside 'wooden seat'.
Can you help me to learn more?
(Other definitions for odense that I've seen before include "Foreign city" , "foreign port?" , "Danish city" , "where Canute founded a cathedral" , "in Denmark?" .)
