It’s not big to get ton in championship (6)
I believe the answer is:
tittle
'it's not big to' is the definition.
I can't tell whether this defines the answer.
'ton in championship' is the wordplay.
'ton' becomes 't'.
'in' indicates putting letters inside.
'championship' becomes 'title' (synonyms).
't' going inside 'title' is 'TITTLE'.
'get' acts as a link.
Can you help me to learn more?
(Other definitions for tittle that I've seen before include "A tiny bit" , "Companion to jot" , "Smallest part (after a jot?)" , "A printed dot as in i" , "Tiny printed mark" .)
