Actually bigger than a Michaelmas daisy (3)
I believe the answer is:
elm
'daisy' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'actually bigger than a michaelmas' is the wordplay.
'ELM' is hidden within the letters.
However, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for elm that I've seen before include "Timber tree" , "Kind of 19" , "Wood in pelmet" , "Victim of fungus" , "Tree of the genus Ulmus" .)
