Crab has its lunch dangling from the front nipper (5)
I believe the answer is:
child
'nipper' is the definition.
(I know that nipper can be written as child)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for child that I've seen before include "Youngster" , "Infant" , "Young human" , "Young person" , "Immature human" .)
