Egyptian fertility goddess (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
isis
'egyptian fertility goddess' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for isis that I've seen before include "where one might take a punt" , "Egyptian deity" , "Egyptian goddess of nature" , "To be, to be an Egyptian goodess" , "Wife of Osiris" .)
