Commend power lift (6)
I believe the answer is:
praise
'commend' is the definition.
(thesaurus)
'power lift' is the wordplay.
'power' becomes 'p'.
'lift' becomes 'raise' ('raise' can be a synonym of 'lift').
'p'+'raise'='PRAISE'
(Other definitions for praise that I've seen before include "Cry 'hallelujah'" , "Be aware of (something)" , "Kudos, pat on the back" , "Approve and commend" , "Congratulate" .)
