Meaning & origin

The spelling Thereasa has never been common, but it saw its peak usage in 1968 and has remained stable in its rarity since then. The name is an alternative to the more familiar Theresa, which has biblical and saintly associations. Despite never ranking in the top 1000, the name's scarcity may appeal to parents seeking a distinctive yet traditional sound. The 1968 peak year reflects the broader popularity of Teresa in the 1960s.

Thereasa is a variant spelling of Theresa, a name of uncertain origin. It is often traced to the Greek verb therizein, meaning 'to harvest' or 'to reap,' or to the name of the Greek island of Thera (modern Santorini). The name was popularized in the Christian world by Saint Teresa of Ávila and has numerous cognates across European languages, including Spanish Teresa, Portuguese Teresa, and German Theresia.
