Abandoned, showed behind, taking a run (8)
I believe the answer is:
marooned
'abandoned' is the definition.
(marooning is a kind of abandoning)
'showed behind taking a run' is the wordplay.
'showed behind' becomes 'mooned' (I can't justify this - if you can you should believe this answer much more).
'taking' is an insertion indicator.
'run' becomes 'r' (cricket abbreviation).
'a'+'r'='ar'
'mooned' placed around 'ar' is 'MAROONED'.
Can you help me to learn more?
(Other definitions for marooned that I've seen before include "Left high and dry" , "Left stranded with little hope of rescue" , "Abandoned like Robinson Crusoe" , "Me on road (anag.)" , "Abandoned on island" .)
