Just like ewe? (5)
I believe the answer is:
ovine
'just like ewe?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ovine that I've seen before include "Sheep-like" , "Relating to sheep" , "1/6 = 2/3 of 28 [SHEEPISH" , "Pertaining to sheep" , "Resembling a sheep" .)
