Mother of Nostradamus? (3)
I believe the answer is:
dam
'mother' is the definition.
(female parent of an animal)
'of nostradamus?' is the wordplay.
'of' says the answer is hidden in the clue.
'DAM' can be found hidden inside 'nostradamus'.
(Other definitions for dam that I've seen before include "Wall restraining water" , "eg Aswan" , "Female parent of an animal, especially livestock" , "Female parent; obstruction" , "Flood barrier" .)
