Wine container preferably passed round church (8)
I believe the answer is:
schooner
'wine container' is the definition.
'schooner' can be an answer for 'container' (schooner is a kind of container). I'm not sure about the 'wine' bit.
'preferably passed round church' is the wordplay.
'preferably' becomes 'sooner' (I can't justify this - if you can you should believe this answer much more).
'passed round' means one lot of letters goes inside another.
'church' becomes 'ch' (common abbreviation).
'sooner' enclosing 'ch' is 'SCHOONER'.
Can you help me to learn more?
(Other definitions for schooner that I've seen before include "boat" , "Two-masted sailing ship" , "9 [CONTAINER" , "Large beer or sherry glass" , "No chores on this sailing ship" .)
