Chin | Definition, Etymology, Synonyms & Antonyms


Chin is a significant feature of our face. It impacts our appearance hugely. It is the part of the face below the mouth and above the neck of the person. This is also called mental protuberance. Medically, it is known as mentum.


It is the lower part of the face which lies below the lower lip. Also, it is the prominence of the lower jaw. It is also defined as the surface under or among the branches of the lower jaw.


It provides the jaw with structural support which makes it more resistant to the stress of chewing. As we see that, young children have little chins which promotes the thinking that as a human chews more food the chin is placed under larger stress, and more bone is laid down to recompense. One of its major functions is to help support the jaw against mechanical stresses.


This word originates from the Old English cin, cinn akin to Old High Germanic origin related to Dutch kin from an Indo-European root shared by the Latin gena cheek and Greek genus jaw.
