A well-known British charity that works to protect children who are being hurt, neglected, or treated badly. People in the UK know the letters; there is a helpline children and adults can call. It is not the police and not a government department, though it works with both. The full name is the National Society for the Prevention of Cruelty to Children. In American English you are more likely to hear about CPS (Child Protective Services) for the state side — NSPCC is the UK charity. Say each letter: N-S-P-C-C.
