Teressa is a feminine name that represents a spelling variant of the more common Teresa or Theresa. Of Greek origin, the name ultimately derives from 'therizo,' meaning 'to harvest,' or possibly from the Greek island of Thera. Teressa carries the warmth and classic appeal of the traditional form while offering a slightly different spelling. The name has religious significance through Saint Teresa of Ávila and Mother Teresa. While less common than Teresa, this variant maintains the name's associations with compassion, spiritual devotion, and inner strength. Teressa experienced modest popularity in the mid-20th century but has become less common in recent decades, giving it a vintage charm.
