Revere greatly (7)
I believe the answer is:
idolise
'revere greatly' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for idolise that I've seen before include "Make into a figure of worship" , "Worship to extremes" , "Revere, love greatly" , "Revere (someone) greatly or excessively" , "Pay inordinate attention to" .)
