Decent one corrupted and drawn in (7)
I believe the answer is:
enticed
'drawn in' is the definition.
'enticed' can be an answer for 'drawn' (I've seen this in another clue). I am unsure of the 'in' bit.
'decent one corrupted' is the wordplay.
'one' becomes 'i' (Roman numeral).
'corrupted' indicates an anagram.
'decent'+'i'='decenti'
'decenti' is an anagram of 'ENTICED'.
'and' is the link.
Can you help me to learn more?
(Other definitions for enticed that I've seen before include "Tempted, lured" , "Given inducement" , "were seductive" , "Persuaded with attractive offer" .)
