Fantastic notices for part (7)
I believe the answer is:
section
'part' is the definition.
(section is a kind of part)
'fantastic notices' is the wordplay.
'fantastic' is an anagram indicator.
'notices' with letters rearranged gives 'SECTION'.
'for' acts as a link.
(Other definitions for section that I've seen before include "Divide; part" , "Cut" , "Notices (anag)" , "Element" , "surgical procedure" .)
