Bond's after diamonds and amorous relationships (10)
I believe the answer is:
dalliances
'amorous relationships' is the definition.
Although both the answer and definition are plural nouns, I can't understand how they can define each other.
'bond's after diamonds' is the wordplay.
I cannot quite understand how this works, but
'bond's' could be 'alliances' ('alliance' can be a synonym of 'bond') and 'alliances' is present in the answer.
'diamonds' could be 'd' (abbreviation for the card suit diamonds) and 'd' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for dalliances that I've seen before include "Flirtations" , "Affairs" .)
