Usage Notes

'Clench' vs. 'Clinch': Which Is Victorious?

'Clench' still has a tight grip in one sense.


The similar spellings of clench and clinch may make you stop to think about which to use in certain contexts. Is it correct to say that a person clinched their fists or that a deal has been clenched? And for you carpenters out there, which is correct: clenching or clinching a nail?

Historically, the two words have shared meanings including those in the above situations, which means that, by definition, you can use either word. However, current usage evidence suggests you might draw some criticism in your word choice. (This is English. You're always going to get some criticism.) After decades of use, a preference has developed for certain senses of clench and clinch, so substituting the words willy-nilly is cautioned against.

Clinch began being used in place of the older clench in the 16th century. Originally, both words denoted the act of gripping the protruding point of a nail with a hammer's claw and turning it over into the wood or of flattening a nail's point with the head of a hammer. In this sense, either word is still used, but clinch is more usual.

By extension of meaning, both clench and clinch came to refer to the act of closing the hands tightly, as in "clenching your fists in anger, frustration, etc." By the 19th century, however, clench took hold, and to this day is the more acceptable choice. Additionally, clench has the meaning of "to hold fast by or as if by grasping tightly."

One context in which clench and clinch have not shared meanings is in boxing, where clinch alone refers to the act of holding an opponent so that no punches can be exchanged. In sports, clinch also expresses the securing of a victory or of a place in a tournament. This "winning" sense of the word has been applied to other kinds of contests as well, like political elections.

After decades of synonymous use, presently clinch is the preferred choice over clench in all but one sense. Clench holds on as a word suggesting just that—closing or holding tight.
