Candies and chocolates and others: source of all of those? (5)
I believe the answer is:
cacao
'all of those?' is the definition.
I can't judge whether this definition defines the answer.
'candies and chocolates and others source of' is the wordplay.
'source of' suggests taking the first letters.
The initial letters of 'candies and chocolates and others' is 'CACAO'.
Can you help me to learn more?
(Other definitions for cacao that I've seen before include "Tree supplying chocolate" , "Tree from which chocolate is made" , "Bean providing chocolate" , "Tropical tree, the source of chocolate" , "Plant" .)
