A Semordnilap is a name designating a word or phrase that spells a different word or phrase backwards. “Semordnilap” is “palindromes” spelled backwards. My wife encountered interesting children’s names as she visited teenage mothers as part of her nursing career. One that I recall was Semaj [ pronounced see majz]. My wife asked, “Is that an old family name?” The young mother said, “No, it’s James- backwards.”
Recently in the Toledo area, a young girl was murdered and had the odd name, Nevaeh. Later, I found out that it is a semordnilap of “Heaven.” Easy ones are Bob, Ada and Hannah. Then there is Werdan for Andrew and Harobed for Deborah. What’s yours?
Sometimes a palindrome of a name renders it ethnic such as Mike becoming Ekim– almost biblical. Or Rednaxela for Alexander. Ekardum [Egyptian?] for Mudrake. Ybbor [Yiddish?] for Robby and Ennazus [Greek?] for Suzanne. The Russian-sounding Assenav comes from Vanessa.
