I land up covering for her (5)
I believe the answer is:
erica
'her' is the definition.
'i land up covering' is the wordplay.
I cannot really understand how this works, but
'i' could be 'a' and 'a' is found within the answer.
The remaining letters 'eric' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for erica that I've seen before include "ling" , "Moorland plant, girl's name" , "Girl's name - I care (anag)" , "Female" , "Heather's Latin name?" .)
