Part of azalea, for example (4)
I believe the answer is:
leaf
'part' is the definition.
(leaf is a kind of part)
'of azalea for example' is the wordplay.
'of' indicates a hidden word.
'LEAF' can be found hidden inside 'azalea for example'.
(Other definitions for leaf that I've seen before include "that's found on plane, for example" , "Part of a plant and of a book" , "Piece of foliage (to be turned over anew?)" , "Page - part of a plant" , "In fall, one dislocated" .)
