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

'ignorant' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?

'heartless confused when echoing' is the wordplay.
I cannot really understand how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is found in the answer.
This explanation may well be incorrect...

'and' is the link.
