Lift finally here behind schedule (5)
I believe the answer is:
elate
'lift' is the definition.
(I've seen this before)
'finally here behind schedule' is the wordplay.
'finally' indicates one should take the final letters.
'behind schedule' becomes 'late' (I've seen this before).
The final letter of 'here' is 'e'.
'e'+'late'='ELATE'
(Other definitions for elate that I've seen before include "Raise the spirits of" , "Exhilarate, put in high spirits" , "Make delighted or proud" , "Make joyful and proud" , "Fill with optimism" .)
