Group of animals that woman ultimately tamed (4)
I believe the answer is:
herd
'group of animals' is the definition.
(I've seen this before)
'woman ultimately tamed' is the wordplay.
'woman' becomes 'her' (**).
'ultimately' indicates one should take the final letters.
The last letter of 'tamed' is 'd'.
'her'+'d'='HERD'
'that' is the link.
(Other definitions for herd that I've seen before include "Group of, eg, cows" , "Group of animals, cattle, say" , "The rabble" , "People in the mass" , "13 Down group" .)
