The word "跨界" is formed by combining the character "跨", which means to step across or cross and is composed of the radical "足" (foot) indicating action related to stepping and the phonetic component "夸" suggesting pronunciation, with the character "界", which means boundary or realm and is composed of the radical "田" (field) indicating a demarcated area and the component "介" implying separation. Together, they create a compound word that literally means "cross boundary" and conveys the concept of transcending or bridging different fields or domains.
