Potter's vehicle picks up everyone for dance venue (8)
I believe the answer is:
ballroom
'dance venue' is the definition.
(I've seen this before)
'potter's vehicle picks up everyone' is the wordplay.
'potter's vehicle' becomes 'broom' (I can't explain this - if you can you should give a lot more credence to this answer).
'picks up' is an insertion indicator.
'everyone' becomes 'all' (all people).
'broom' placed around 'all' is 'BALLROOM'.
'for' is the link.
Can you help me to learn more?
(Other definitions for ballroom that I've seen before include "Dance hall" , "place associated with steps?" , "potential murder scene on board" , "Dancing venue" , "Place for dance" .)
