Meaning & origin

Thresea is a rare spelling variant of Theresa that saw a brief period of use in the mid-20th century. It was first recorded in 1935, but its peak year of usage was 1971, reflecting a time when Theresa itself was highly popular. The name has never entered the top 1000 rankings, indicating it remained an uncommon choice even at its highest point. While its trajectory is stable, it has not seen any revival. Thresea is a name that appeals to parents seeking a distinctive spelling of a classic name, though its use has been sporadic and never widespread.

Thresea is a modern spelling variant of Theresa, ultimately derived from the Greek name Θερεσια (Theresia), which is itself a feminine form of Theras, meaning 'harvester' or 'summer'. The name's popularity in the English-speaking world traces to Saint Teresa of Avila, but Thresea as a distinct spelling emerged in the mid-20th century, first recorded in 1935. It saw modest use in the 1960s and 1970s, peaking in 1971.
