The word 晋级 is formed by combining two characters that each contribute a core meaning to create a new, unified concept. The first character, 晋 (jìn), carries the inherent idea of moving forward, advancing, or progressing. The second character, 级 (jí), provides the notion of a grade, level, or rank. When fused, their meanings blend seamlessly to convey the specific action of "advancing to a higher level", such as in a competition, a job, or a stage of a process.
