Mud thrown at her (5)
I believe the answer is:
earth
'mud' is the definition.
(I've seen this before)
'thrown at her' is the wordplay.
'thrown' is an anagram indicator.
'at'+'her'='ather'
'ather' with letters rearranged gives 'EARTH'.
(Other definitions for earth that I've seen before include "Soil; fox's lair" , "Solid ground" , "our present abode" , "Third planet from the Sun" , "Badger or fox burrow" .)
