gripper

A gripper is something made to grab or hold an object firmly. You will often see the word used for the end part of a machine, such as the claw on a robot arm or the grabbing part of an arcade machine. It can also mean a small tool or attachment that helps you hold, lift, or move something safely. The idea is simple: it is the part that gives a secure hold when hands alone are not enough.

The word "gripper" usually refers to something designed to grasp, hold, or secure an object. Most often, it names the grabbing part of a tool or machine. In factories and workshops, for example, a robotic arm may have a gripper that picks up parts and places them somewhere else. A claw machine at an arcade also has a gripper that tries to catch a prize. In this sense, the word points to a practical holding device whose job is to take hold of something firmly and control it.

The word can also be used for smaller everyday tools or attachments that help with grip. Someone might use a jar opener with a gripper surface, or attach ice grippers to shoes to get better traction on frozen ground. In these cases, the meaning is still centered on the same idea: giving a firmer, safer hold.

Less commonly, "gripper" may describe a person or thing that grips tightly, but that use is not the main one in modern everyday English. For most learners, the safest understanding is this: a gripper is a device, part, or attachment that helps grab, hold, lift, or keep control of something.
