Quarters of an acre out of doors (5)
I believe the answer is:
roods
'quarters of an acre out' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'of doors' is the wordplay.
'of' indicates an anagram (the answer comes from or 'of' the letters).
'doors' with letters rearranged gives 'ROODS'.
Can you help me to learn more?
(Other definitions for roods that I've seen before include "Crosses" , "Doors (anag.)" .)
