Good person speaks — does so with hesitations (8)
I believe the answer is:
stutters
'so with hesitations' is the definition.
I can't judge whether this definition defines the answer.
'good person speaks' is the wordplay.
'good person' becomes 'st' (saint).
'speaks' becomes 'utters' ('utter' can be a synonym of 'speak').
'st'+'utters'='STUTTERS'
'does' acts as a link.
Can you help me to learn more?
(Other definitions for stutters that I've seen before include "impediments" , "Stammers in repeating the first consonants of words" , "Speaks with hesitant repetition of first consonants" , "Speaks haltingly" , "falters" .)
