Starts to help everyone and dazzles chief (4)
I believe the answer is:
head
'chief' is the definition.
(I know that chief can be written as head)
'starts to help everyone and dazzles' is the wordplay.
'starts to' says to take the initial letters.
The first letters of 'help everyone and dazzles' is 'HEAD'.
(Other definitions for head that I've seen before include "Cranium" , "bean" , "Source of river, leader" , "Froth on beer" , "Skull" .)
