Tessy

Tessy is a charming feminine name that functions both as a standalone name and as a diminutive form of Tess, Teresa, or Theresa. These parent names derive from the Greek 'therizo,' meaning 'to harvest,' or possibly from the Greek island of Thera. Tessy carries a friendly, approachable quality with its cheerful 'y' ending, giving it a perpetually youthful feel. The name has enjoyed some popularity in Luxembourg due to Princess Tessy, who was married to Prince Louis of Luxembourg. Despite its diminutive nature, Tessy has established itself as a given name in its own right in various regions. The name blends sweetness with simplicity, offering an unpretentious and warm impression that works well from childhood through adulthood, though it maintains a particularly playful and affectionate character.

Pronounced TES-ee.
