Stupidly tiptoe in to make a request (8)
I believe the answer is:
petition
'make a request' is the definition.
(petitioning is a kind of making a request)
'stupidly tiptoe in' is the wordplay.
'stupidly' indicates anagramming the letters.
'tiptoe'+'in'='tiptoein'
'tiptoein' is an anagram of 'PETITION'.
'to' is the link.
(Other definitions for petition that I've seen before include "Entreaty" , "Written request" , "Suit - supplication" , "Request (often by many)" , "Formal request with many signatures" .)
