Sisie Origin and Meaning

The name Sisie is a girl's name.

Sisie appears to be a diminutive or variant form of names like Cecilia, Cecile, or possibly a nickname for Sister or Sissy that evolved into a given name. Its origins are somewhat obscure, though it likely shares etymology with Cecilia (from Latin, meaning 'blind') or developed as an affectionate family nickname that gained independent usage. The name has a distinctly sweet, informal quality with its repeating 's' sounds and simple structure. Sisie remains quite rare as a formal given name, appearing occasionally through the 20th century. It might appeal to parents seeking something diminutive and endearing with a vintage feel, offering the charm of a nickname with the uniqueness of an uncommon given name.
