Right to leave amphibian in confused state (3)
I believe the answer is:
fog
'confused state' is the definition.
'fog' can be an answer for 'state' (fog is a kind of state). I am not certain of the 'confused' bit.
'right to leave amphibian' is the wordplay.
'right' becomes 'R' (common abbreviation).
'to leave' indicates named letters should be taken away.
'amphibian' becomes 'frog' (frog is a kind of amphibian).
'frog' with 'r' taken away is 'FOG'.
'in' is the link.
Can you help me to learn more?
(Other definitions for fog that I've seen before include "Impenetrable mist" , "Thick mist" , "Miasma" , "Confusion" , "Bank restricting visibility" .)
