Tell engineer about talk show (5)
I believe the answer is:
ellen
'talk show' is the definition.
(I know that Ellen is a talk show)
'tell engineer about' is the wordplay.
'about' indicates the answer is hidden within the clue (the clue goes around or about the answer).
'ELLEN' is hidden within 'tell engineer'.
(Other definitions for ellen that I've seen before include "- Terry, Eng. actress" , "English actress, ____ Terry (1847-1928)" , "MacArthur, round-the-world yachtswoman" , "Dame - Terry, English actress" , "Dame - MacArthur, round-the-world sailor" .)
