Tressy

Tressy is a diminutive or pet form of the name Theresa. The name Theresa itself has a somewhat debated etymology, but it is most commonly believed to derive from the Greek word 'therizein' (to harvest) or 'theros' (summer). It gained popularity in Europe due to Saint Teresa of Ávila, a prominent Spanish mystic and Carmelite nun of the 16th century. The diminutive form 'Tressy' emerged as a more informal and affectionate version of Theresa, particularly in English-speaking countries.
