Fish found in Hungary (3)
I believe the answer is:
gar
'fish' is the definition.
(type of gar)
'in hungary' is the wordplay.
'in' indicates a hidden word.
'GAR' can be found hidden inside 'hungary'.
'found' is the link.
(Other definitions for gar that I've seen before include "Type of fish" , "something fishy here" , "Creature" , "A fish; cloth scrap (reversed)" , "swimmer" .)
