Small hallowed bottles (3)
I believe the answer is:
low
'small' is the definition.
('low' can be a synonym of 'small')
'hallowed bottles' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'LOW' is hidden within 'hallowed'.
(Other definitions for low that I've seen before include "Deep sound of cattle - not high" , "Humble; dejected" , "something from Guernsey?" , "Inferior, cow's call" , "Make a bovine sound" .)
