Beam in relief having risen in rank (7)
I believe the answer is:
radiate
'beam' is the definition.
(I know that beam can be written as radiate)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for radiate that I've seen before include "Disseminate" , "Emit light/heat" , "Give out (light, etc)" , "Spread outwards" , "Emit (rays or waves)" .)
