Hurried back to house for conference (7)
I believe the answer is:
seminar
'conference' is the definition.
(seminar is a kind of conference)
'hurried back to house' is the wordplay.
'hurried' becomes 'ran' (running is a kind of hurrying).
'back' is a reversal indicator.
'to' says to put letters next to each other (I've seen this in other clues).
'house' becomes 'semi' (short for semi-detached).
'ran' reversed gives 'nar'.
'nar' after 'semi' is 'SEMINAR'.
'for' is the link.
(Other definitions for seminar that I've seen before include "Study group on specific subject" , "Symposium" , "Short intensive study course for marines" , "Working meeting in College" , "Discussion meeting" .)
