stirn

Stirn is the German noun for the forehead, the part of the face located above the eyes. The term is used in everyday language as well as in medical and anatomical contexts to refer to this region of the head.

Anatomically, the forehead corresponds mainly to the frontal region of the skull and is largely formed by the frontal bone. It extends from the hairline at the top of the head down to the base of the brow ridges above the eye sockets. The area includes skin, subcutaneous tissue, and muscles such as the frontalis, which raises the eyebrows, and the sometimes-involved procerus muscle.

Stirn is also used in idiomatic expressions. For example, die Stirn bieten means to confront or resist something boldly. The term appears in phrases describing facial expressions, such as Stirnrunzeln, which refers to frowning or wrinkling the forehead.
