Stretches of land documents (6)
I believe the answer is:
tracts
This could be a double definition.
'stretches of land' is the first definition.
(I've seen this in another clue)
'documents' is the second definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for tracts that I've seen before include "Extended areas of land" , "Large areas of land or small pamphlets" , "Plots" , "leaflets" , "Large stretches of land or religious pamphlets" .)
