go, just, suitable

適 is composed of the radical 辵 (walk) and 啇 (essence). 辵 represents traveling or going toward a destination, while 啇 conveys the authority of a monarch's words, extending to connote appropriateness or correctness. When one travels along the proper route, they naturally reach the suitable or ideal location smoothly; thus, 適 came to mean "to go to" as well as "suitable" or "appropriate."
