Notably, conspicuously (8)
I believe the answer is:
signally
This clue is a double definition.
'notably' is the first definition.
(I've seen this before)
'conspicuously' is the second definition.
(I've seen this in another clue)
(Other definitions for signally that I've seen before include "Notably" , "Sallying (anag.)" , "noticeably" .)
