The word 随着 is formed by combining the character 随, which carries the core meaning of "to follow" or "to go along with", with the character 着, a grammatical suffix that, when attached to a verb, often indicates a continuous or ongoing state or action. This fusion creates a single unit that conceptually suggests a process of "following along in a continuous manner", thereby forming a prepositional sense meaning "along with" or "in the wake of" a developing situation.
