短

Phono-semantic compound:

矢 (화살 시, “arrow”) — semantic component, indicating length/measurement.

豆 (콩 두, “bean vessel”) — phonetic component.

短期 (단기) — short term

短所 (단소) — weakness, shortcoming

短篇 (단편) — short story, short piece

長短 (장단) — length, pros and cons

矢 often appears as a semantic element in characters related to size/height, e.g. 矮 (왜, “short, dwarf”).

The base image of an arrow (矢) emphasizes relative length, here used in the sense of “shortness.”
