Heaven spelled backwards (variant)
Nevaen is a modern creative variation of Nevaeh, which is the word 'Heaven' spelled in reverse. This specific spelling adds an extra 'n' at the end, likely to mimic the phonetic ending of names like Raven or Aspen. It emerged in the United States following the massive popularity of the original Nevaeh in the early 2000s.
