Elegant young lady making first appearance broadcasting live (8)
I believe the answer is:
debonair
'elegant' is the definition.
(I've seen this before)
'young lady making first appearance broadcasting live' is the wordplay.
I cannot really see how this works, but
'lady' could be 'deb' and 'deb' is found within the answer.
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is located in the answer.
'broadcasting' could be 'on' and 'on' is present in the answer.
The remaining letters 'ar' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for debonair that I've seen before include "The dashing" , "Having carefree, suave manner" , "Jaunty and sophisticated" , "Sprightly" , "I broaden out with self-confident manner" .)
