Praise, glorify (4)
I believe the answer is:
laud
I believe this clue is a double definition.
'praise' is the first definition.
(I know that laud is a more specific form of praise)
'glorify' is the second definition.
(I know that glorify can be written as laud)
(Other definitions for laud that I've seen before include "Praise highly" , "Praise acclaim" , "Praise formally" , "Name of archbishop; praise" , "Praise - celebrate" .)
