章

Also refers to the 19-year cycle (Metonic cycle) in astronomy.

Evolved from pictorial forms:

Original oracle/bronze forms showed marking or tattooing on a body, suggesting something inscribed.

Later, it developed into the combination of:

音 (음, sound) with 十 (십, ten) — in seal script, representing sound and inscription.

日 (일, sun/day) under 辛 (신, bitter, mark) — possibly indicating a body being tattooed.

From the idea of “engraved marks” to “written signs” and “text, composition.”

文章 (문장) — writing, composition

章節 (장절) — chapter, section

徽章 (휘장) — insignia, badge

憲章 (헌장) — charter, constitution

章句 (장구) — passages of a text

章法 (장법) — rules of composition (esp. calligraphy)

Specialized astronomical usage: refers to the 19-year Metonic cycle in the ancient Chinese lunisolar calendar.
