Encourage happiness (5)

I believe the answer is:

cheer

I believe this is a double definition.

'encourage' is the first definition.
(I know this)

'happiness' is the second definition.
(thesaurus)

(Other definitions for cheer that I've seen before include "Shout hooray" , "Applaud with shouts" , "Perk up" , "provisions for feast" , "Encourage - applaud" .)

I've seen this clue in The Daily Express.
