Men retire and set out for Roman road (6,6)
I believe the answer is:
ermine street
'roman road' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'men retire and set out' is the wordplay.
'and' means one lot of letters go next to another.
'out' indicates an anagram (out can mean wrong or inaccurate).
'men'+'retire'+'set'='menretireset'
'menretireset' with letters rearranged gives 'ERMINE STREET'.
'for' is the link.
Can you help me to learn more?
(Other definitions for ermine street that I've seen before include "Roman road from London to Lincoln" , "Major Roman road from London to York" , "Roman road running from London to York" , "Roman road in England" .)
