Article on green bananas named botanical types, say (6)
I believe the answer is:
genera
'article on green bananas named botanical types say' is the definition.
I can't judge whether this defines the answer.
'article on green bananas' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'on' means one lot of letters go next to another.
'bananas' indicates anagramming the letters (bananas can informally mean crazy).
'green' is an anagram of 'gener'.
'a' after 'gener' is 'GENERA'.
Can you help me to learn more?
(Other definitions for genera that I've seen before include "similar groups" , "Biological groups" , "Blood vessel" , "classes" , "Orders with common characteristics" .)
