Laud, idolise (7)
I believe the answer is:
worship
I believe this is a double definition.
'laud' is the first definition.
(thesaurus)
'idolise' is the second definition.
(I know that idolise can be written as worship)
(Other definitions for worship that I've seen before include "prayer" , "Adore, adulate" , "religious service" , "Religious rites and ceremonies" , "Revere" .)
