Aufweichen

Aufweichen is a German verb meaning to make something softer, looser, or less firm. It is a separable verb formed from auf- and weich. The term is used in both literal and figurative senses: to soften physical material, to relax or dilute a rule or stance, or to ease pressure or stiffness in a process. The past participle is aufgeweicht.

In technical and materials contexts, Aufweichen describes the reduction of hardness or strength due to moisture, heat, or chemical agents. For example, soils with high clay content can soften when wetted, reducing their bearing capacity; polymers may become more flexible when plasticizers are added; wood can swell and lose rigidity under high humidity. In geotechnical reports the term may be used to indicate a loss of shear strength under moist conditions.

In food and textiles, Aufweichen refers to the process of softening through soaking, humidification, or other moisture-related means. Dry components like bread, legumes, or cereals are made pliable or ready for further processing by adding liquid. In textiles, moisture can soften fibers or fabrics, facilitating processing or application of finishes.

In policy, law, and everyday speech, Aufweichen can describe the loosening or relaxing of rules, standards, or positions. A regulation might be softened or relaxed to permit exceptions or to widen scope. This figurative use is common in political and administrative language.

Overall, Aufweichen denotes a shift toward reduced stiffness or resistance, whether in physical materials, consumer products, or normative frameworks.
