Reportedly lift beams (4)
I believe the answer is:
rays
'beams' is the definition.
(rays of light)
'reportedly lift' is the wordplay.
'reportedly' shows a homophone (sound like).
'lift' becomes 'raise' (synonyms).
'raise' is a homophone of 'RAYS'.
(Other definitions for rays that I've seen before include "They swim" , "Pencils of light" , "Flat fish" , "Narrow beams of light" , "Sunbeams" .)
