Punk's too giddy about leading part for Emily Blunt (9)
I believe the answer is:
outspoken
'blunt' is the definition.
(synonyms)
'punk's too giddy about leading part for emily' is the wordplay.
I cannot quite understand how this works, but
'part' could be 'ut' (ut is a kind of part) and 'ut' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for outspoken that I've seen before include "Bold in speech" , "Candid" , "bluff" , "Forthright, frank" , "Blunt" .)
