Promote and congratulate with no pressure (5)
I believe the answer is:
raise
'promote' is the definition.
(I've seen this before)
'congratulate with no pressure' is the wordplay.
'congratulate' becomes 'praise' (I've seen this before).
'with no' indicates named letters should be taken away.
'pressure' becomes 'p' (abbreviation).
'praise' with 'p' taken away is 'RAISE'.
'and' is the link.
(Other definitions for raise that I've seen before include "Increased earnings in America" , "Haul up" , "Care for during childhood" , "Lift, elevate" , "Make greater" .)
