Plant that comes up in May (3)
I believe the answer is:
yam
'plant that comes up' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'may' is the wordplay.
'may' can be anagrammed to 'YAM'.
But, I am not sure how the anagram is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for yam that I've seen before include "vegetable plant" , "Tropical root vegetable" , "US sweet potato" , "May be a sweet spud" , "Edible root" .)
