Commend, laud (6)
I believe the answer is:
praise
This clue is a double definition.
'commend' is the first definition.
(I know that commend is a more specific form of the action praise)
'laud' is the second definition.
(I know that laud is a more specific form of the action praise)
(Other definitions for praise that I've seen before include "Kudos, pat on the back" , "Commend or laud" , "Worship, glorify" , "Aspire (anag)" , "Express warm approval of (someone/something)" .)
