Assists gullible types, they say (8)
I believe the answer is:
succours
'assists' is the definition.
(succouring is a kind of assisting)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for succours that I've seen before include "Gives aid in distress" , "Helps" , "gives help" , "Comforts" .)
