to die, death the process of dying In a number of languages clear distinctions are made in the use of terms for dying on the basis of the manner or circumstances of death. For example, one term may refer to death primarily as the result of old age, while another term may refer to death caused by sickness, and still other terms may be used for death caused by violence. Careful distinctions must be used in determining the choice of terms based on particular contexts.
