Land upright and turn (5)
I believe the answer is:
tract
'land' is the definition.
(tract can mean an area of land)
'upright and turn' is the wordplay.
'upright' becomes 'trac' (I can't justify this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'turn' becomes 't' (abbreviation in Oxford Dictionary of Abbreviations).
'trac'+'t'='TRACT'
Can you help me to learn more?
(Other definitions for tract that I've seen before include "religious work, often" , "Piece of writing" , "Large area of land or small booklet" , "Political pamphlet" , "Anatomical structure" .)
