Poems about a racecourse (5)
I believe the answer is:
epsom
'a racecourse' is the definition.
(Epsom is an English racecourse)
'poems about' is the wordplay.
'about' indicates anagramming the letters.
'poems' with letters rearranged gives 'EPSOM'.
(Other definitions for epsom that I've seen before include "Mopes around in English horse-racing venue" , "can have horses" , "track in Surrey" , "The Oaks and Derby are run here" , "Location of English Derby" .)
