The word “knell” is a noun that refers to the sound of a bell, especially a funeral bell, rung slowly and solemnly. It can also be used as a verb, meaning to ring or sound in this manner.
Interesting fact: The word “knell” is derived from the Old English word “cnyllan,” which means “to strike or sound a bell.” The tolling of funeral bells has been a long-standing tradition in many cultures to announce a death and mark the passing of a loved one.
