Managed to turn up at end of house discussion group (7)
I believe the answer is:
seminar
'discussion group' is the definition.
(I've seen this before)
'managed to turn up at end of house' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'to turn up' says the letters should be written in reverse.
'at end of' says to put letters next to each other.
'house' becomes 'semi' (I've seen this before).
'ran' reversed gives 'nar'.
'nar' put after 'semi' is 'SEMINAR'.
(Other definitions for seminar that I've seen before include "Study group on specific subject" , "University course" , "Group discussing" , "Academic class" , "Meeting for study" .)
