Fluffy toy, familiarly (3)
I believe the answer is:
pom
'fluffy toy familiarly' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pom that I've seen before include "English person" , "Little dog" , "Disparaging term for English immigrants to the Antipodes" , "Brit abroad" , "Britisher in Oz" .)
