The word "frorer" is not commonly used in English, and thus, there are no widely recognized synonyms for this term. However, it is similar to the word "freeze", which means to lower the temperature of something to the point where it turns solid or becomes very cold. Other synonyms for "freeze" include solidify, congeal, harden, crystallize, and stiffen. These words all describe the process of transforming a liquid or soft material into a solid form by lowering its temperature. Regardless of the specific term used, all these words convey the same fundamental meaning of a decrease in temperature resulting in a solid or very cold substance.
