Käftarnas

Käftarnas is the genitive plural form of the Swedish noun käftar, which means jaws. In Swedish, nouns change form to reflect number and definiteness, and the genitive is used to indicate possession or association, as in the phrase “the jaws’ role” or “the muscles of the jaws.”

Form and usage: The indefinite plural of käftar is käftar, while the definite plural is käftarna (the jaws). The genitive form of the definite plural is käftarnas, yielding phrases such as käftarnas muskler (the muscles of the jaws) or käftarnas funktion (the function of the jaws). Unlike English, Swedish uses a suffix to mark possession; there is no apostrophe in written Swedish for this purpose.

Examples: Käftarnas muskler are essential for mastication. Studier av käftarnas anatomi analyze how the jaw muscles coordinate bite force. In zoological and anatomical texts, the phrase käftarnas rörelser may be used to describe the movements of the jaws.
