Item spoiled something tiny (4)
I believe the answer is:
mite
'something tiny' is the definition.
I can't judge whether this definition defines the answer.
'item spoiled' is the wordplay.
'spoiled' indicates an anagram.
'item' anagrammed gives 'MITE'.
Can you help me to learn more?
(Other definitions for mite that I've seen before include "Minute arachnid" , "The Biblical widow's offering" , "Microscopic animal" , "Little chap" , "Very small creature or child" .)
