Small piece child’s not quite finished in street (7)
I believe the answer is:
snippet
'small piece' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for snippet that I've seen before include "Scrap (of information, news etc)" , "piece of information" , "Newspaper extract" , "Fair --, knitwear style" , "A small piece cut off" .)
