The feminine given name Britnay is of Scottish and English origin, derived from the name Bridget, which means 'strength' or 'exalted one'. It has gained popularity as a variant spelling of Brittany, which can also be traced back to the same root. The name Britnay has been used sparingly but consistently throughout history, appearing in various spellings such as Britney, Britni, and Britny.
"Britnay saw its peak popularity with 16 babies named in 1989, but it has since declined, with only 5 or fewer occurrences from 1993 onwards."
