See painter framing pleasant flowering plant (8)
I believe the answer is:
lonicera
'flowering plant' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'see painter framing pleasant' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'painter' becomes 'RA' (member of the Royal Academy of Arts).
'framing' is an insertion indicator (inserted letters are framed by the outside letters).
'pleasant' becomes 'nice' (similar in meaning).
'lo'+'ra'='lora'
'lora' enclosing 'nice' is 'LONICERA'.
Can you help me to learn more?
(Another definition for lonicera that I've seen is " Honeysuckle".)
