The word 冷冻 is formed by combining two characters that each convey a related state or action concerning low temperature. The first character, 冷 (lěng), means "cold", establishing the base condition of low temperature. The second character, 冻 (dòng), means "to freeze", indicating the specific process or result of becoming solid due to cold. When placed together, they create a logical sequence where the state of "cold" leads to the action of "freezing", forming a compound that conceptually merges into the single idea of "freezing" or "refrigeration".
