There's little point in removing it from rabbit stew (4)
I believe the answer is:
barb
'there's little point in removing' is the definition.
I can't judge whether this definition defines the answer.
'it from rabbit stew' is the wordplay.
'from' indicates named letters should be taken away.
'stew' is an anagram indicator.
'rabbit' with 'it' taken out is 'rabb'.
'rabb' with letters rearranged gives 'BARB'.
Can you help me to learn more?
(Other definitions for barb that I've seen before include "Small prong on larger point" , "Arrowhead projection" , "Part of an arrow head" , "part of a habit" , "Thorn or spike" .)
