Tessia is a feminine given name phonologically realized in English as ˈtɛsiə, characterized by a trochaic trisyllabic structure with primary stress on the initial syllable. Etymologically, it constitutes a morphological extension of the diminutive Tessa—itself derived from the Late Latin Therēsia and ultimately from the Greek therizein, “to harvest”—where the addition of the -ia suffix aligns with Anglo-American onomastic patterns that confer a refined yet distinctive cadence. Analysis of U.S. Social Security Administration data from 1964 to 2010 reveals its sporadic but sustained usage, with annual registrations ranging from five to fifteen and national rankings predominantly between the 700th and 900th percentiles, indicating a deliberate selection by parents seeking a name that marries classical resonance with moderate rarity.
