Leads or follows? It's decided by tossing a coin (5,2,5)
I believe the answer is:
heads or tails
'decided by tossing a coin' is the definition.
I can't judge whether this defines the answer.
'leads or follows?' is the wordplay.
'leads' becomes 'heads' (heading is a kind of leading).
'follows?' becomes 'tails' (I've seen this in another clue).
'heads'+'or'+'tails'='HEADS OR TAILS'
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for heads or tails that I've seen before include "phrase?" , "Choice" , "Coin-tossing question" .)
