Strew over an area (7)
I believe the answer is:
scatter
'strew over an area' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for scatter that I've seen before include "Throw in a random way" , "Disperse, thrown around" , "Throw in various directions" , "Broadcast" , "Strew over an area" .)
