Destroy the note that was carried (5)

I believe the answer is:

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

'destroy' is the definition.
(thesaurus)

'the note that was carried' is the wordplay.
I cannot quite understand how this works, but
'note' could be 'e' (musical note) and 'e' is present in the answer.
The remaining letters 'rode' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for erode that I've seen before include "Gradually destroy", "Abrade", "Eat away", "Slowly remove", "Corrode".)
