Group tutorial (5)
I believe the answer is:
class
This could be a double definition.
'group' is the first definition.
(class is a kind of group)
'tutorial' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for class that I've seen before include "sort" , "Genre" , "Genus" , "Category; form" , "Study group" .)
