Dicky berated, biting ends of dinky toy (5,4)
I believe the answer is:
teddy bear
'toy' is the definition.
(teddy bear is a kind of toy)
'dicky berated biting ends of dinky' is the wordplay.
'dicky' is an anagram indicator (dicky can mean ill or non-functioning).
'biting' is an insertion indicator (I've seen this in other clues).
'ends of' says to hollow out the word (remove centre letters).
'dinky' with its centre removed is 'dy'.
'berated' is an anagram of 'tedbear'.
'tedbear' going around 'dy' is 'TEDDY BEAR'.
(Other definitions for teddy bear that I've seen before include "Rupert, perhaps" , "Cuddly ursine" , "Stuffed toy" , "Child's toy, musically in picnic" , "Cuddly toy, named after President Roosevelt" .)
