Humiliate a cricket side on purpose (6)
I believe the answer is:
offend
'humiliate' is the definition.
(thesaurus)
'a cricket side on purpose' is the wordplay.
'a cricket side' becomes 'off' (**).
'on' says to put letters next to each other.
'purpose' becomes 'end' (I've seen this before).
'off'+'end'='OFFEND'
(Other definitions for offend that I've seen before include "Cause displeasure or hurt, be nasty towards" , "Commit crime - hurt feelings" , "Hurt someone's feelings" , "Be displeasing to" , "Act in disregard of the law" .)
