English daisy for example good seasonal item (6,3)
I believe the answer is:
easter egg
'seasonal item' is the definition.
(item given in the Easter season)
'english daisy for example good' is the wordplay.
'english' becomes 'E' (abbreviation).
'daisy' becomes 'aster' (I've seen this before).
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'good' becomes 'g' (abbreviation).
'e'+'aster'+'eg'+'g'='EASTER-EGG'
(Other definitions for easter egg that I've seen before include "seasonal treat" , "chocolate gift" , "Seasonal present" , "Candy to celebrate Spring festival" , "festival food" .)
