Lord or lady (5)
I believe the answer is:
noble
'lord or lady' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for noble that I've seen before include "Impressive in appearance" , "Titled peer of the realm" , "Illustrious - old money" , "Of high rank or birth" , "Imposing, magnificent" .)
