Betrothed discovered in cafe (6)
I believe the answer is:
fiance
'betrothed' is the definition.
(fiance is a kind of betrothed)
'in cafe' is the wordplay.
'in cafe' anagrams to 'FIANCE'.
However, I am unsure how the anagram is indicated.
'discovered' acts as a link.
Can you help me to learn more?
(Other definitions for fiance that I've seen before include "Engaged male" , "Male intended" , "One waiting to go to match" , "The man she is going to marry" , "who may be planning marriage" .)
