Dispersed remains of a student group (7)
I believe the answer is:
seminar
'a student group' is the definition.
The definition and answer can be both groups as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'dispersed remains' is the wordplay.
'dispersed' indicates an anagram.
'remains' anagrammed gives 'SEMINAR'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for seminar that I've seen before include "Working meeting in College" , "Training conference" , "Student discussion group - remains (anag)" , "Meeting for study" , "Short intensive study course for marines" .)
