Lie in a furrow with the hunt milling around (7)
I believe the answer is:
untruth
'lie' is the definition.
(an untruth is a lie)
'furrow with the hunt milling around' is the wordplay.
'furrow' becomes 'rut' (synonyms).
'with' means one lot of letters go next to another.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'hunt milling' becomes 'unh' (I can't explain this - if you can you should give a lot more credence to this answer).
'around' indicates putting letters inside.
'rut' put after 't' is 'trut'.
'trut' going within 'unh' is 'UNTRUTH'.
'in a' is the link.
Can you help me to learn more?
(Other definitions for untruth that I've seen before include "A lie or false statement" , "A genuinely deniable" , "story" , "Fiction" , "product of Orwell's ministry?" .)
