Small carp, cooked a little bit (5)
I believe the answer is:
scrap
'a little bit' is the definition.
'scrap' can be an answer for 'bit' (synonyms). I'm unsure of the 'a little' bit.
'small carp cooked' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'cooked' is an anagram indicator (letters cooked into a new form).
'carp' is an anagram of 'crap'.
's'+'crap'='SCRAP'
Can you help me to learn more?
(Other definitions for scrap that I've seen before include "Drop" , "Small amount; fight" , "bundle" , "A fragment or an informal fight" , "Dispense with - waste material" .)
