Sauna made to break down again and again and again! (2,7)
I believe the answer is:
ad nauseam
'down again and again and again' is the definition.
I can't judge whether this definition defines the answer.
'sauna made to break' is the wordplay.
'to break' indicates an anagram.
'sauna'+'made'='saunamade'
'saunamade' anagrammed gives 'AD NAUSEAM'.
Can you help me to learn more?
(Other definitions for ad nauseam that I've seen before include "Interminably" , "To a very tiresome degree" , "Much too much" , "Past the stage of enjoying" , "seasickness pills like this would be counterproductive?" .)
