Broadly embracing weather protection (8)
I believe the answer is:
umbrella
'protection' is the definition.
(umbrella is a kind of protection)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for umbrella that I've seen before include "It keeps the raini off" , "Let a smile be yours, as the song advises" , "Protecting cover" , "It protects against the rain" , "Parasol" .)
