Reign changing hands, which has some attraction (4)
I believe the answer is:
lure
This could be a double definition.
'reign changing hands which' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'some attraction' is the second definition.
(lure is a kind of attraction)
'has' acts as a link.
Can you help me to learn more?
(Other definitions for lure that I've seen before include "Attraction" , "It's used to attract fish" , "Tempt invoking rule" , "Attract with bait" , "Tempt with bait" .)
