Devoted followers that Raducanu has now secured? (5)
I believe the answer is:
islam
'devoted followers' is the definition.
The answer and definition can be both groups as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for islam that I've seen before include "Monotheistic religion" , "Faith with five pillars" , "Religion based on Muhammad's teachings" , "Creed" , "organised religion" .)
