mastication

The word 'mastication' originates from the Latin verb masticare, meaning 'to chew'. This Latin term was itself borrowed from the Greek mastikhan, which carried the more forceful sense of 'gnashing the teeth'. The suffix '-ation', a common nominalizing ending in English derived from Latin, was appended to form a noun describing the process or act. Thus, the literal "action of chewing" described by its components evolved directly into the modern, specialized biological term for the first stage of digestion.
