Repeatedly unveiled ideas about southern tourist destination (4,3)
I believe the answer is:
dead sea
'tourist destination' is the definition.
The definition suggests a singular noun which matches the answer.
'repeatedly unveiled ideas about southern' is the wordplay.
'repeatedly' indicates the doubling of some letters.
'unveiled' means to look at the middle letters (the word's outer letters are taken off).
'about' indicates putting letters inside.
'southern' becomes 's' (abbreviation).
The centre of 'ideas' is 'dea'.
'dea' duplicated is 'deadea'.
'deadea' placed around 's' is 'DEAD SEA'.
Can you help me to learn more?
(Other definitions for dead sea that I've seen before include "Salty lake on the Israel/Jordan border" , "Salt lake fed by the Jordan river" , "'Body of water, sounds like it's passed on (4,3)'" , "The lake that's a late ocean" , "Sounds like a late ocean but it's a lake" .)
