One searching beyond a hundred, go on and on (7)
I believe the answer is:
chunter
'on and on' is the definition.
I can't tell whether this definition defines the answer.
'one searching beyond a hundred' is the wordplay.
'one searching' becomes 'hunter' (a person who searches or hunts).
'beyond' is a charade indicator (letters next to each other).
'a hundred' becomes 'C' (Roman numeral).
'hunter' put after 'c' is 'CHUNTER'.
'go' is the link.
Can you help me to learn more?
(Other definitions for chunter that I've seen before include "Rabbit" , "Go on" , "Grumble monotonously" , "Talk monotonously" , "Mutter" .)
