'i told you' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'her toe's broken' is the wordplay.
'broken' indicates anagramming the letters.
'her'+'toes'='hertoes'
'hertoes' is an anagram of 'SO THERE'.

Can you help me to learn more?
