Deduce from, when you convene (6)
I believe the answer is:
gather
This clue could be a double definition.
'deduce' is the first definition.
(thesaurus)
'convene' is the second definition.
(I've seen this before)
'from when you' is the link.
This may not be right. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for gather that I've seen before include "Congregate" , "Convene" , "Get together" , "Assemble - conclude - contract" , "Come/bring together" .)
