Discussion groups provided by new marine on board ship (8)
I believe the answer is:
seminars
'discussion groups' is the definition.
The definition and answer can be both groups as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'new marine on board ship' is the wordplay.
'new' indicates an anagram.
'on board' indicates putting letters inside (inserted letters are taken on board).
'ship' becomes 'ss' (prefix in ship names eg SS Great Britain).
'marine' is an anagram of 'eminar'.
'eminar' placed within 'ss' is 'SEMINARS'.
'provided by' acts as a link.
Can you help me to learn more?
(Other definitions for seminars that I've seen before include "classes" , "discussions are academic" , "workshops" .)
