By the sound of it, completely destroy lift (5)
I believe the answer is:
raise
'lift' is the definition.
(synonyms)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for raise that I've seen before include "Bring up - an increase in pay" , "Inflate" , "Advance" , "Produce" , "Pick up" .)
