Day daughter occupies Manchester town land (6)
I believe the answer is:
saddle
'land' is the definition.
(I've seen this before)
'day daughter occupies manchester town' is the wordplay.
'day' becomes 'd' (abbreviation for day).
'daughter' becomes 'd' (genealogical abbreviation).
'occupies' means one lot of letters goes inside another.
'manchester town' becomes 'sale' (I can't justify this - if you can you should believe this answer much more).
'd'+'d'='dd'
'dd' inserted within 'sale' is 'SADDLE'.
Can you help me to learn more?
(Other definitions for saddle that I've seen before include "Leathery" , "Burden: pass" , "Seat for riding" , "Equestrian seat" , "Rider's seat" .)
