Strong ale I'm brewing for lizard (4,7)
I believe the answer is:
gila monster
'lizard' is the definition.
(Gila monster is an example)
'strong ale i'm brewing' is the wordplay.
'brewing' indicates an anagram.
'strong'+'ale'+'im'='strongaleim'
'strongaleim' with letters rearranged gives 'GILA MONSTER'.
'for' is the link.
(Other definitions for gila monster that I've seen before include "Large venomous lizard" , "US resident" , "venomous attacker" .)
