架子 (jià·zi) is a noun with three main meanings, all derived from the core idea of 'support structure'. Literally, 架 means 'to support' or 'frame', and 子 is a common noun suffix. So the word originally refers to a physical frame or stand — most commonly a shelf, bookcase, or rack used to hold items. This is its most concrete and frequent meaning in daily life, especially in homes, kitchens, or stores.

In extended usage, 架子 also describes a person’s posture, bearing, or demeanor — as in standing tall with confidence or stiffness. Even more figuratively, it conveys 'airs' or 'pretentiousness': someone putting on an act of superiority or aloofness, often humorously or critically. Context determines which sense applies: physical objects (e.g., kitchen shelves), body language (e.g., military stance), or social attitude (e.g., acting too important). The word is neutral in tone but can carry mild disapproval when referring to arrogance.
