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