Tessa
Meaning
pet form of Theresa, meaning uncertain
The story
Tessa began as the tail of Theresa and became its own name. Theresa's own origin is genuinely uncertain, possibly from a Greek word for harvest or the island of Therasia, and Tessa inherits that pleasant vagueness, a name whose sound clearly outran its etymology. In America it was rare until surprisingly recently: 165 babies in the 1950s, then a steady climb through the end of the century, 12,041 in the 1990s and holding near 13,000 across the 2000s and 2010s, with about 6,200 so far this decade. It is a girl's name, brisk and modern-sounding despite its age, two crisp syllables that never shorten because they are already short. It rides with its neighbours Nessa, Cora and Sadie, vintage pet forms that a century later stand on their own.
