One nun I'd distressed with offensive hint (8)
I believe the answer is:
innuendo
'offensive hint' is the definition.
'innuendo' can be an answer for 'hint' (I've seen this before). I am not sure about the 'offensive' bit.
'one nun i'd distressed' is the wordplay.
'distressed' is an anagram indicator.
'one'+'nun'+'id'='onenunid'
'onenunid' is an anagram of 'INNUENDO'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for innuendo that I've seen before include "Indirect implication" , "Malicious suggestion" , "End union with insinuation" , "Indirect remark" , "Oblique allusion" .)
