reaper

A reaper is someone or something that cuts down plants, especially grain crops.

When we talk about reapers in everyday life, it's usually referring to big machines used on farms to harvest wheat, corn, and other grains. These massive vehicles move across fields, cutting the stalks and collecting them into bundles. Sometimes, people use the word "reaper" figuratively to describe something or someone that cuts down others, like a powerful critic who severely reviews art.

The word reaper can also be used as a noun to refer to the person operating one of these machines, but more commonly it's used for the machine itself.
