Article on the common people, one gathers (7)
I believe the answer is:
amasses
'gathers' is the definition.
('amass' can be a synonym of 'gather')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for amasses that I've seen before include "Collects" , "'Accumulates, gathers (7)'" , "Gathers together" .)
