Frog's relative (4)
I believe the answer is:
toad
'frog's relative' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for toad that I've seen before include "not found in Ireland" , "driver of reckless repute" , "Wind in Willows hall-owner" , "Stout-bodied amphibian" , "Hateful person; animal" .)
