A flower presented itself (5)
I believe the answer is:
arose
'itself' is the definition.
I can't tell whether this definition defines the answer.
'a flower presented' is the wordplay.
'flower' becomes 'rose' (I've seen this before).
'presented' is a charade indicator (letters next to each other).
'a'+'rose'='AROSE'
Can you help me to learn more?
(Other definitions for arose that I've seen before include "Issued" , "Happened" , "''. ... by any other name would smell as sweet'' (Romeo and Juliet)" , "Came about" , "Became apparent" .)
