clinch

Clinch is a term with multiple meanings across sports, metalwork, fishing, and general usage. As a verb, it means to secure, settle, or bring to a decisive conclusion; as a noun, it can refer to a close physical grip or a fastening.

In combat sports, the clinch is a grappling position in which fighters are in close contact, often with arms around the opponent’s neck or torso. It is used to control distance, neutralize an opponent, tire them, or set up strikes, throws, or takedowns. Boxing rules regulate the clinch to limit excessive wrestling, while in mixed martial arts the clinch is a common phase for short punches, knees, elbows, and various attempts at control or takedowns. Clinch work emphasizes head control, underhooks, framing, and off-balancing.

In manufacturing and metalworking, clinching is a method of fastening in which a material is deformed or bent to hold parts together. It is used for permanent joints in riveted or sheet-metal assemblies and can involve deforming the rivet tail or sealing a seam to secure components without additional fasteners.

In fishing, the clinch knot is a simple tying method that secures a line to a hook or lure by wrapping the tag end around the standing line and threading it back through, providing reliable strength for many species.

More generally, to clinch a deal means to secure an agreement or to ensure a decisive outcome. Clinch as a term can also appear in place names and surnames, and there are geographic features associated with the word in various regions.
