Work man used to be in races with antelope (3,5,4)
I believe the answer is:
the waste land
'work man used' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'be in races with antelope' is the wordplay.
'be' becomes 'hewas' (I am not sure about this - if you are sure you should believe this answer much more).
'in' indicates putting letters inside.
'races' becomes 'tt' (Isle of Man TT).
'with' is a charade indicator (letters next to each other).
'antelope' becomes 'eland' (eland is a kind of antelope).
'hewas' inserted into 'tt' is 'thewast'.
'thewast'+'eland'='THE WASTE LAND'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for the waste land that I've seen before include "Eliot poem -- talented Shaw (anag)" , "Scrub" , "TS Eliot's (barren?) poem?" , "Poem by T.S. Eliot" , "TS Eliot's long 1922 poem" .)
