Page gets lumbar pain due to flower (8)
I believe the answer is:
plumbago
'flower' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe there's an association between them I don't understand?
'page gets lumbar pain' is the wordplay.
I cannot quite understand how this works, but
'page' could be 'p' and 'p' is present in the answer.
'pain' could be 'lumbago' (lumbago is a kind of pain) and 'lumbago' is found in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'due to' acts as a link.
Can you help me to learn more?
(Other definitions for plumbago that I've seen before include "lead" , "Plant type that includes sea pinks" , "Evergreen shrub" , "Shrub; graphite" , "Word for graphite" .)
