canards

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

'scoundrels covering borders of nicaragua run fake news' is the definition.
I can't tell whether this definition defines the answer.

'scoundrels covering borders of nicaragua run' is the wordplay.
'scoundrels' becomes 'cads' (a cad is a dishonourable person).
'covering' means one lot of letters goes inside another.
'borders of' suggests removing the centre.
'run' becomes 'r' (cricket abbreviation).
'nicaragua' with its centre removed is 'na'.
'na'+'r'='nar'
'cads' enclosing 'nar' is 'CANARDS'.

Can you help me to learn more?

(Other definitions for canards that I've seen before include "Deliberately misleading fabrications" , "False reports" , "unfounded stories" , "Unfounded rumours" .)
