The word "凭着" is formed through the grammatical combination of the verb or preposition "凭" (píng), meaning "to rely on" or "on the basis of," and the aspect particle "着" (zhe), which indicates a continuous or ongoing state. When joined, "凭着" functions as a compound preposition or conjunction that means "by means of," "by relying on," or "on the strength of," and it introduces the method, basis, or instrument used to accomplish something. The particle "着" adds a sense of an active, sustained reliance or utilization, making the phrase dynamic and often used to describe how an action is persistently carried out through a particular quality, condition, or resource.
