Britnee is of American origin, derived from the British Isles. It combines the elements 'Britt' meaning 'from Britain', and '-ee', a suffix commonly found in female names. Britnee was popularized during the late 20th century, reaching its peak popularity in the United States during the early to mid-1990s.
