The word **阵子** is formed through a common Chinese lexical structure where the core character **阵** (zhèn), which carries the primary meaning of "a period," "a spell," or "a burst of time," is combined with the nominal suffix **子** (zi). The suffix **子** here does not add concrete meaning but grammatically nominalizes the term, softening it into a colloquial and measure-word-like unit used for expressing an indefinite, short-to-moderate duration. Thus, **一阵子** (yī zhènzi) translates as "a while" or "a period of time," with the structure emphasizing a vague, experiential chunk of time rather than a precise measurement.
