Tehran bus broken down on the beach
I believe the answer is:
sunbather
'the beach' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'tehran bus broken down' is the wordplay.
'broken down' indicates an anagram.
'tehran'+'bus'='tehranbus'
'tehranbus' anagrammed gives 'SUNBATHER'.
'on' is the link.
Can you help me to learn more?
(Other definitions for sunbather that I've seen before include "Loafer on the beach" , "Tanner" , "One enjoying holiday" , "One trying to get brown" , "One hoping for a tan" .)
