I'm a little stuck... Click here to teach me more about this clue!

'getting the wrong end of the stick' is the definition.
I can't tell whether this defines the answer.

'i'm repenting stir made' is the wordplay.
'made' is an anagram indicator.
'im'+'repenting'+'stir'='imrepentingstir'
'imrepentingstir' with letters rearranged gives 'MISINTERPRETING'.

'by' is the link.

Can you help me to learn more?
