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

'for dishonesty' is the definition.
(lying is being dishonest)

I cannot understand how the rest of the clue works.

(Other definitions for lying that I've seen before include "Duplicity" , "Matilda's behaviour" , "Prone or supine" , "Flat" , "Prone; fibbing" .)

I've seen this clue in The Independent.
