versteifen

Versteifen is a German verb that means to become stiff or to cause something to become stiff. It is used in both physical and figurative contexts.

In a literal, physical sense, versteifen describes increasing rigidity or reducing flexibility of a material, body part, or structure. Engineers may versteifen a frame by adding reinforcement to improve stiffness. In biology or medicine, tissues, muscles, or joints can versteifen due to factors such as cold, injury, aging, or disease. The construction or medical sense can be transitive (das Material wird versteift) or reflexive (sich versteifen).

In a figurative sense, versteifen refers to becoming inflexible in opinions, attitudes, or behavior. A person who "versteift sich auf eine Position" clings stubbornly to their view, often resisting compromise or new information. This usage highlights psychological rigidity rather than physical stiffness.

Etymology and usage notes: versteifen is formed with the prefix ver- added to a base meaning stiffen or harden. The exact historical root can vary, but today it is understood as making something stiffer or more rigid, whether literally or metaphorically. The noun associated with the verb is Versteifung, denoting the act or result of stiffening.

See also: Versteifung (stiffening), Verstärkung (reinforcement), Festigkeit (strength), Verhärtung (hardening). Versteifen is common in technical writing about engineering, materials science, and biomechanics, as well as in psychological or social discussions describing inflexibility.
