Like a lamb? (4)
I believe the answer is:
meek
'like a lamb?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for meek that I've seen before include "Modest or spiritless" , "Quiet" , "Gentle and self-effacing" , "Humble and acquiescent" , "Requiring more spirit, maybe" .)
