I believe the answer is:
prevaricate
'deceive' is the definition.
(thesaurus)
'blab about english vicar after contriving' is the wordplay.
'blab' becomes 'prate' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'english' becomes 'e' (abbreviation).
'after contriving' is an anagram indicator.
'e'+'vicar'='evicar'
'evicar' is an anagram of 'evaric'.
'prate' enclosing 'evaric' is 'PREVARICATE'.
'to' acts as a link.
(Other definitions for prevaricate that I've seen before include "Dither" , "Deliberately withhold information" , "Behave evasively" , "Dodge" , "Quibble, equivocate" .)
