Worship, idolise (5)
I believe the answer is:
adore
I believe this is a double definition.
'worship' is the first definition.
(I've seen this before)
'idolise' is the second definition.
(I've seen this in another clue)
(Other definitions for adore that I've seen before include "Worship and glorify" , "Treasure" , "Love, worship" , "Love (someone) deeply" , "Very much like" .)
