A bridge perhaps at Cuba closed as Ross passed (9)
I believe the answer is:
crossover
'ross passed' is the definition.
I can't tell whether this definition defines the answer.
'a bridge perhaps at cuba closed' is the wordplay.
'a bridge perhaps' becomes 'ross' (I can't justify this - if you can you should believe this answer much more).
'at' says to put letters next to each other (I've seen this in other clues).
'cuba' becomes 'c'.
'closed' becomes 'over'.
'ross' put after 'c' is 'cross'.
'cross'+'over'='CROSSOVER'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for crossover that I've seen before include "affecting different functions" , "Rock opera perhaps" , "mixing styles" , "in a mixture of styles" , "Meeting point" .)
