Men touring 504 islands? (8)
I believe the answer is:
maldives
'islands?' is the definition.
(island nation)
'men touring 504' is the wordplay.
'men' becomes 'males' (I've seen this in another clue).
'touring' indicates putting letters inside (touring can mean going round).
'504' becomes 'div' (I can't explain this - if you can you should believe this answer much more).
'males' placed around 'div' is 'MALDIVES'.
Can you help me to learn more?
(Other definitions for maldives that I've seen before include "Mad Elvis found in the islands" , "Indian Ocean island country" , "Island nation to S. of India" , "Indian Ocean country of many islands" , "Mad Elvis is here in the Indian ocean" .)
