kennet (Australian, slang),
This word, which comes from Latin, originally referred to the slaughtering of one in ten soldiers, a practice of the army of Ancient Rome. In current language, however, the meaning of the word has broadened and it is now used not only to describe the destruction of people and animals, but also of institutions: overseas visitors will stay away in droves, decimating the tourist industry. Synonyms such as destroy (for people and animals) and reduce (for institutions) are appropriate alternatives.
