Which fungus is an amphibian's weapon? (9)
I believe the answer is:
toadstool
'which fungus' is the definition.
I can't judge whether this definition defines the answer.
'an amphibian's weapon?' is the wordplay.
'an amphibian's' becomes 'toads' (toad is a kind of amphibian).
'weapon?' becomes 'tool' (I've seen this before).
'toads'+'tool'='TOADSTOOL'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for toadstool that I've seen before include "Something poisonous" , "what's poisonous maybe" , "Capped fungus" , "Common fungus" , "a potentially toxic development" .)
