Angry about the lies designed to delude (7)
I believe the answer is:
mislead
'delude' is the definition.
(thesaurus)
'angry about the lies designed' is the wordplay.
'angry' becomes 'mad' ('mad' can be similar in meaning to 'angry'**).
'about' means one lot of letters goes inside another.
'designed' indicates anagramming the letters (designed with the letters).
'lies' with letters rearranged gives 'isle'.
'mad' enclosing 'isle' is 'MISLEAD'.
'to' acts as a link.
(Other definitions for mislead that I've seen before include "Deceive" , "Cause someone to have a false belief" , "Fool" , "Give a wrong impression to (someone)" , "Cause someone to believe something is not true" .)
