Essential ingredient of spicy life-stories? (7)
I believe the answer is:
variety
'essential ingredient' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for variety that I've seen before include "class" , "Diversity in old music hall?" , "arrangement" , "kind of show" , "Kind (of entertainment?)" .)
