When irritated, Ted leaps onto a platform (8)
I believe the answer is:
pedestal
'platform' is the definition.
(thesaurus)
'when irritated ted leaps onto a' is the wordplay.
'ted leaps' can be anagrammed to 'PEDESTAL'.
However, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for pedestal that I've seen before include "Base on which something is mounted" , "Statue's support" , "Stand for statue or basin" , "Support for bust" , "Supporting column of a washbasin" .)
