Sisi

In English and German, Sisi is a playful nickname, often used as an alternative spelling to Cece (from Cecilia, "blind"), or as a nickname for the classic Elisabeth or Isabella (meaning "pledged to God"). Alternatively, it could be used for any S- name, including Sophie, Sienna, Sierra, or Susannah, or perhaps for something like Josie, Maisie, Daisy and so on.

Additionally, it may be used as an affectionate nickname for a sister, making it a more generic nickname, like Sonny, Honey, Poppet, or Sweetie and so on. In this case, it could work as a sweet choice for a big sister whose young sibling can't yet pronounce her name.

While it may read as cutesy and nickname-territory in English speaking countries, as a Chinese name, it has more solidity. Pronounced as SUR-SUR or SUZ-SUZ, it means "think, reflect, consider", and is alternatively transliterated as Sze Sze.

Other sources suggest it is an Akan name, meaning "born on Sunday", possibly connecting to names such as Esi, Akosua, or Kwasi, which have the same meaning.

A notable bearer was the 19th century Empress of Austria and Queen of Hungary, Elisabeth, who was known as Sisi, while more recently, influencer and model Sisi Rose has drawn attention to the name.

Pronounced SEE-see.

As of October 2026, Sisi ranked #15507 in US births in 2003 SSA, peaked at #10907 in 2001, Nameberry popularity #996.
