Pet deals arranged by Foundation (8)
I believe the answer is:
pedestal
'foundation' is the definition.
(thesaurus)
'pet deals arranged' is the wordplay.
'arranged' indicates an anagram.
'pet'+'deals'='petdeals'
'petdeals' anagrammed gives 'PEDESTAL'.
'by' acts as a link.
(Other definitions for pedestal that I've seen before include "Column support, on which one is worshipped" , "Supporting column of a washbasin" , "Place for hero" , "Those worshipped are put on one" , "Statue's base" .)
