Succession sometimes linked to the throne (5)
I believe the answer is:
chain
'succession' is the definition.
(I've seen this in other clues)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for chain that I've seen before include "Line of links" , "Shackle" , "Part of cycle" , "group of shops here" , "Fetter" .)
