Articulated beams put up (5)
I believe the answer is:
raise
'put up' is the definition.
(I know that put up can be written as raise)
'articulated beams' is the wordplay.
'articulated' indicates a 'sounds like' (homophone) clue.
'beams' becomes 'rays' (rays of light).
'rays' sounds like 'RAISE'.
(Other definitions for raise that I've seen before include "Call up" , "Produce" , "Wage increase" , "Erect; grow" , "Pick up" .)
