What does clench mean?
Clench is a verb meaning to close, grip, or press something tightly, most commonly applied to parts of the body: clenching one's fists in anger, clenching one's teeth against pain, or clenching one's jaw in frustration or determination. It can also describe gripping an object firmly, such as clenching a rope or a tool. The word carries strong connotations of tension, effort, and suppressed emotion, which makes it a favourite of novelists describing characters under stress. It also exists as a noun denoting a tight grip or clamp. Closely related in form and history is "clinch," which today generally means to secure conclusively or to embrace tightly; the two words share a common origin but have diverged in meaning. Clench is standard throughout the English-speaking world and suits both literal description and figurative, emotionally charged writing.
To close or grip tightly, especially to press the teeth together or squeeze the hand into a fist; also, to hold or fasten something firmly.
"She clenched her teeth against the cold."
Most frequently used of fists, teeth, and jaw.
A tight grip or clamping action.
"The blacksmith gave the nail a firm clench."
Less common than the verb; in metalwork, a clench can refer to a fastening made by bending back a projecting end.
"Clench" and "clinch" were once the same word — they split apart over centuries into a word for gripping tight and a word for settling a deal.
