I'm a little stuck... Click here to teach me more about this clue!

'like ewe?' is the definition.
(I've seen this in another clue)

I can't explain the remainder of the clue.

(Other definitions for ovine that I've seen before include "Sheep-like" , "like a mug" , "Like the Cheviots" , "Like a sheep" , "1/6 = 2/3 of 28 [SHEEPISH" .)

I've seen this clue in The Sun.
