An article we reverence (3)
I believe the answer is:
awe
'reverence' is the definition.
('awe' can be a synonym of 'reverence')
'an article we' is the wordplay.
'an article' becomes 'a' (indefinite article).
'a'+'we'='AWE'
(Other definitions for awe that I've seen before include "Amazement" , "Respectful fear or wonder 93)" , "Fear - veneration" , "Stupefied admiration" , "Great wonder" .)
