Is a collector, one deduces (7)
I believe the answer is:
gathers
'is' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for gathers that I've seen before include "Infers" , "Gleans" , "Understands" , "Collects in one place" , "Draws together" .)
