A woman’s token of matrimony? Something fishy here (7)
I believe the answer is:
herring
'something fishy here' is the definition.
(herring is a kind of fish)
'a woman's token' is the wordplay.
'a woman' becomes 'her' (her refers to a woman).
'token' becomes 'ring' (I have seen 'token of love' mean 'ring' so perhaps 'token' could also mean 'ring').
'her'+'ring'='HERRING'
'of matrimony?' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for herring that I've seen before include "Fish that's kippered" , "Fish that can be red and kippered!" , "Fish, often kippered" , "Fatty fish" , "Small silvery fish" .)
