The word "溜走" is formed by merging the character "溜", which conveys a sense of slipping, sliding, or moving stealthily, with the character "走", meaning to walk or depart. This combination blends the nuanced manner of movement suggested by "溜" with the fundamental action of leaving indicated by "走", resulting in a cohesive term that vividly depicts the act of sneaking away or departing quietly and often hurriedly.
