Disregard tailless cod with pole and lure (8)
I believe the answer is:
contempt
'disregard' is the definition.
(I've seen this before)
'tailless cod with pole and lure' is the wordplay.
'tailless' means to remove the last letter (the tail of the word is removed).
'with' is a charade indicator (letters next to each other).
'pole' becomes 'n' (abbreviation for North, as in North Pole).
'and' is a charade indicator (letters next to each other).
'lure' becomes 'tempt' (synonyms).
'cod' with its last letter taken away is 'co'.
'co'+'n'+'tempt'='CONTEMPT'
(Other definitions for contempt that I've seen before include "Feeling of disdain, perhaps of court" , "In which you may be held" , "Offence of disrespect in court" , "The feeling of despising someone" , "Disdain, say, perhaps of court" .)
