The floral type is sweet (3)
I believe the answer is:
pea
This clue could be a double definition.
'the floral type' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'sweet' is the second definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'is' is the link.
Can you help me to learn more?
(Other definitions for pea that I've seen before include "Climbing plant; vegetable" , "The plant is a strange ape" , "food item" , "Seed eaten as vegetable" , "12 in a pod" .)
