Lift the beams, say (5)
I believe the answer is:
raise
'lift' is the definition.
(I know that lift can be written as raise)
'beams say' is the wordplay.
'beams' becomes 'rays' (rays of light).
'say' shows a homophone (sound like).
'rays' is a homophone of 'RAISE'.
'the' acts as a link.
(Other definitions for raise that I've seen before include "climb" , "Move higher" , "Aries (anag)" , "Amplify" , "Collect - increase in pay" .)
