Woman shifting soil (4)
I believe the answer is:
lois
'woman' is the definition.
'shifting soil' is the wordplay.
'shifting' is an anagram indicator.
'soil' is an anagram of 'LOIS'.
(Other definitions for lois that I've seen before include "-- Lane, 'Superman' character" , "- Lane, girlfriend of Superman" , "Superman's girlfriend" , "- Lane (Superman's girl)" , "- Lane, Daily Planet reporter" .)
