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' (similar in meaning).
'about' indicates putting letters inside.
'designed' is an anagram indicator (designed with the letters).
'lies' with letters rearranged gives 'isle'.
'mad' going around '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" .)
