Track access cut by account (10)
I believe the answer is:
racecourse
'track' is the definition.
(synonyms)
'access cut by account' is the wordplay.
'access' becomes 'recourse' (I've seen this before).
'cut by' is an insertion indicator (some letters cut into others).
'account' becomes 'ac' (abbreviation for account).
'recourse' going around 'ac' is 'RACECOURSE'.
(Other definitions for racecourse that I've seen before include "Doncaster, for example?" , "Running track for horses" , "Bath, perhaps" , "Where to find better" , "Eg, Aintree" .)
