记号

• Pinyin: jì hao
• Desglose de hanzi: 记 = 讠+ 己 (speech + self — to record); 号 = 口 + 丂 (mouth + exhale — mark/name)

Significado

Marca; señal; signo (informal).

Used broadly for any kind of marking — from a pencil note in a book to a notch cut in wood as a reminder. Distinct from 符号 (formal symbol system) — 记号 is more informal and personal.
