Origin

The character 姓 combines the radical for "woman" or "female" on the left with the character 生 (meaning "life" or "birth") on the right, which serves as a sound hint for pronunciation. In ancient China, surnames were originally passed down through the maternal line, which is why the "woman" radical was used to represent family names. The 生 component helps indicate how the character should be pronounced, rather than adding to its meaning. Over time, surnames became a formal system for identifying family lineages, and this character became the standard way to write the word for "surname."
