Original Palindromes Alphabetical

Seed:  ananym
Time:  1 minute

I chose ananym as my preferred term for a word that makes a different word when reversed. On a whim I reversed ananym and saw "My nana," which caught my attention (even though my family never used the endearment 'nana' for our grandmothers). Then I decided to include an ananym in the palindrome. The finished composition came to me in a flash.

Why did I choose ananym from the nineteen terms (anagram, ananym, antigram, drow, half-palindrome, heterodrome, inversion, palinode, recurrent palindrome, retronym, reversagram, reversal, reversal pair, reversible, reversible anagram, reversion, semordnilap, sotadic palindrome, and word reversal, according to The Dictionary of Wordplay by Dave Morice) already in use? It was not random.

First, I eliminated the multi-word terms because I wanted a single word. Then I looked at the palindromic potential of each of the remaining terms. I also considered the nature of the term's usage, whether authoritative sources accepted the term, and the word's etymology. Only ananym satisfied all five criteria.

Bonus reason:  "Ban ananym" is also "banana-nym".
