I believe the answer is:
ian
'singer janis' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ian that I've seen before include "- McEwan, Eng. writer" , "The familar Dr Paisley" , "Scottish man's name" , "Sir - McKellen, actor" , "- Fleming (James Bond)" .)
