Limit means by which you might get word into chatterbox (8)
I believe the answer is:
edgeways
'you might get word into chatterbox' is the definition.
I can't tell whether this definition defines the answer.
'limit means by' is the wordplay.
'limit' becomes 'edge' (I have seen 'Outside limit ' mean 'edge' so perhaps 'limit' could also mean 'edge').
'means' becomes 'ways' (I've seen this in other clues).
'by' says to put letters next to each other.
'edge'+'ways'='EDGEWAYS'
'which' is the link.
Can you help me to learn more?
(Other definitions for edgeways that I've seen before include "With the side facing forwards" , "obliquely" , "How to get a word in?" , "With sharp side towards viewer" , "With side uppermost" .)
