My lady, very busy morning? (5)
I believe the answer is:
madam
'my lady' is the definition.
'very busy morning?' is the wordplay.
'very busy' becomes 'mad'.
'morning?' becomes 'am'.
'mad'+'am'='MADAM'
(Other definitions for madam that I've seen before include "Make wildly happy" , "pompous young lady?" , "Titled lady" , "Palindrome used in speaking politely to a woman" , "'Call Me ---' (I. Berlin)" .)
