"India’s prime minister has promised a "jaw-breaking response" to the killing of 40 Indian paramilitary police." What does “jaw-breaking response” mean?
"Jaw-breaking response" means to give such an answer that the person will be unable to argue further. मुह तोड़ जवाब
The response will be more than words. The term jaw-breaking refers to violence, as in a punch to the jaw. The prime minister is assuring the victims and their families that the response will be much more than mere words and likely a physical if not violent pursuit and prosecution of the offenders.
