Scornful of son having organised raid on clubs (8)
I believe the answer is:
sardonic
'scornful' is the definition.
(I've seen this before)
'son having organised raid on clubs' is the wordplay.
'son' becomes 's'.
'having' means one lot of letters go next to another.
'organised' indicates an anagram.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'raid'+'on'='raidon'
'raidon' is an anagram of 'ardoni'.
's'+'ardoni'+'c'='SARDONIC'
'of' acts as a link.
(Other definitions for sardonic that I've seen before include "Grimly cynical" , "Sarcastic" , "sneering" , "Disdainfully or ironically humorous" , "Mocking or scornful" .)
