Khan dancing nude outside by implication (8)
I believe the answer is:
innuendo
'implication' is the definition.
(innuendo is a kind of implication)
'khan dancing nude outside' is the wordplay.
I cannot quite see how this works, but
an anagram of 'nude' is 'uend' which is located in the answer.
This explanation may well be incorrect...
'by' acts as a link.
Can you help me to learn more?
(Other definitions for innuendo that I've seen before include "nudge nudge)" , "Disparaging oblique remark" , "suggestive remarks" , "comment of sexual nature?" , "Aspersion" .)
