Make a comment that's awfully verbose (7)
I believe the answer is:
observe
'make a comment' is the definition.
(make an observation)
'awfully verbose' is the wordplay.
'awfully' is an anagram indicator.
'verbose' anagrammed gives 'OBSERVE'.
'that's' is the link.
(Other definitions for observe that I've seen before include "Notice, watch" , "Watch closely" , "Espy" , "Mark" , "Keep an eye on" .)
