🏪 老 old + 字 sign + 号 name/mark = an old shop-sign brand, time-honored
Each character stacks: 老 old, 字 written sign, 号 business name or mark. Together they name a firm whose old painted shop-sign still hangs after generations of trade.
老 — old man 耂 + 匕 (bent figure)
Originally a pictograph of an elderly person with long hair leaning on a cane. The top 耂 depicts the hair and stooped body, while 匕 at the bottom represents the cane or a bent figure. The core meaning 'old' has remained stable since oracle bone script.
字 — roof 宀 + child 子
Originally depicted a child 子 under a roof 宀, suggesting birth or rearing a child in the home. The meaning later extended to 'to give birth, nurture' and then to 'written character', since characters were seen as offspring derived from earlier pictographs.
号 — mouth 口 + tiger 虎
Originally written 號, combining 口 (mouth, indicating a cry or call) with 虎 (tiger) as the phonetic and a hint at a loud roar. It first meant to shout or call out, then extended to a name, title, or signal. The simplified form 号 keeps only the upper element.
