Loser galloped too (7)
I believe the answer is:
alsoran
'loser galloped too' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'loser galloped too' is the wordplay.
'loser' becomes 'also' (I can't justify this - if you can you should believe this answer much more).
'galloped' becomes 'ran' (I've seen this in another clue).
'too' says to put letters next to each other.
'also'+'ran'='ALSORAN'
Can you help me to learn more?
(Another definition for alsoran that I've seen is " failure?".)
