Gather before conference, maybe, to show up again (8)
I believe the answer is:
reappear
'to show up again' is the definition.
I can't judge whether this defines the answer.
'gather before conference' is the wordplay.
'gather' becomes 'reap' (reaping is a kind of gathering).
'before' says to put letters next to each other.
'conference' becomes 'pear' (conference pear is a type of pear).
'reap'+'pear'='REAPPEAR'
'maybe' acts as a link.
Can you help me to learn more?
(Other definitions for reappear that I've seen before include "crop up again" , "return" , "make a comeback" , "Show over" , "Come into view again" .)
