Put down post for tourist landmark (5,3)
I believe the answer is:
lands end
'tourist landmark' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'put down post' is the wordplay.
'put down' becomes 'land' ('land' can be a synonym of 'put down').
'post' becomes 'send' ('send' can be a synonym of 'post').
'land'+'send'='LANDS END'
'for' is the link.
Can you help me to learn more?
(Other definitions for lands end that I've seen before include "From extremely English place" , "Cape" , "The SW promontory of England (4,'1,3)" , "western extremity" , "Other extreme from 12" .)
