Beginning with the ring - the ring I had reset (6)
I believe the answer is:
origin
'beginning' is the definition.
(I know that beginning can be written as origin)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for origin that I've seen before include "For a start" , "Where X meets Y" , "Where axes cut" , "Where one begins" , "Beginning (of species?)" .)
