Poems about some old salts (5)
I believe the answer is:
epsom
'some old salts' is the definition.
(I've seen this in another clue)
'poems about' is the wordplay.
'about' indicates anagramming the letters.
'poems' is an anagram of 'EPSOM'.
(Other definitions for epsom that I've seen before include "track in Surrey" , "- Salts are a purgative" , "Poems about English Derby venue" , "Mopes around English Derby venue" , "English town, of course?" .)
