Synonym study

1. Die, pass away ( pass on; pass ), perish mean to relinquish life. To die is to become dead from any cause and in any circumstances. It is the simplest, plainest, and most direct word for this idea, and is used figuratively of anything that has once displayed activity: An echo, flame, storm, rumor dies. Pass away (or pass on or pass ) is a commonly used euphemism implying a continuation of life after death: Grandfather passed away ( passed on or passed ). Perish, a more literary term, implies death under harsh circumstances such as hunger, cold, neglect, etc.; figuratively, perish connotes utter extinction: Hardship caused many pioneers to perish. Ancient Egyptian civilization has perished.

die-off

[ dīôf′ ]

A sudden, severe decline in a population or community of organisms as a result of natural causes. Local die-offs can be caused by such factors as an unusual or extreme weather pattern, an outbreak of disease, or toxic algal blooms in a body of water.
