Galloping the pinto round the ring from choice (6)
I believe the answer is:
option
'choice' is the definition.
(I know that choice can be written as option)
'galloping the pinto round the ring' is the wordplay.
'galloping' is an anagram indicator (I've seen this in other clues).
'round' means one lot of letters goes inside another.
'the ring' becomes 'o' (letter resembling a ring).
'pinto' anagrammed gives 'optin'.
'optin' placed around 'o' is 'OPTION'.
'from' is the link.
(Other definitions for option that I've seen before include "Altenative choice" , "Right to choose" , "Something choosable" , "Choice, selection" , "Preference" .)
