Creed Ive worked out for a dishonest person (8)
I believe the answer is:
deceiver
'dishonest person' is the definition.
'deceiver' can be an answer for 'person' (deceiver is a kind of person). I am not certain of the 'dishonest' bit.
'creed ive worked out' is the wordplay.
'worked out' is an anagram indicator.
'creed'+'ive'='creedive'
'creedive' anagrammed gives 'DECEIVER'.
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for deceiver that I've seen before include "Person who leads you to believe something that's untrue" , "Deceitful" , "Chiseller" .)
