Ram or ewe (5)
I believe the answer is:
sheep
I believe this is a double definition.
'ram' is the first definition.
(I know that ram can be written as sheep)
'ewe' is the second definition.
(I know that ewe can be written as sheep)
(Other definitions for sheep that I've seen before include "Ruminant animal" , "Animals said to lack initiative" , "Dolly or Shaun" , "Easily led people" , "Ovine animals" .)
