Sze

The name Sze (or Si) is a Chinese surname with a long and rich history. It is believed to have originated from several different sources, including ancient states and official titles. One prominent origin traces back to the Spring and Autumn period (771–476 BC) of China, where a state called Si existed. Descendants of the rulers of this state adopted Si as their surname. Another origin is linked to an official title, 'Si Kong' (司空), which was a minister of public works. Over time, some descendants of these officials also adopted Si as their surname.

While primarily a surname, Sze can also be used as a given name, though it is less common. When used as a given name, its meaning can vary depending on the specific character used, but common interpretations relate to concepts like 'elder brother' or 'firstborn,' reflecting a sense of seniority or importance within the family. Its usage as a given name is more often seen in certain dialects or regions, and it carries a traditional and somewhat formal feel.
