Daisy is first to kiss star (8)
I believe the answer is:
asterisk
'star' is the definition.
('asterisk' can be a synonym of 'star')
'daisy is first to kiss' is the wordplay.
'daisy' becomes 'aster' (I've seen this before).
'first to' indicates taking the first letters.
The first letter of 'kiss' is 'k'.
'aster'+'is'+'k'='ASTERISK'
(Other definitions for asterisk that I've seen before include "Star-like symbol as reference mark" , "Textual reference symbol" , "Printer's star" , "Star-shaped symbol as reference mark." , "Character drawing attention to footnote" .)
