Verbose sort of notice (7)
I believe the answer is:
observe
'notice' is the definition.
(I know that notice is a kind of observe)
'verbose sort' is the wordplay.
'sort' indicates anagramming the letters.
'verbose' is an anagram of 'OBSERVE'.
'of' acts as a link.
(Other definitions for observe that I've seen before include "Keep - watch" , "See - say" , "Keep an eye on" , "Watch attentively" , "Scrutinise or comply with" .)
