I just happened to stumble across this word while surfing the internet and decided to create a website about it. I never really thought about spelling my panganiban last name backwards since it has been hard for non-filipinos to pronounce my last name as it is!
Since the number of search rank positions had been taken over by an actress with the last name Panganiban a lot of ‘katukayos’ or ‘kapangalan’ had chosen to use Nabinagnap as their moniker.
I believe the word for this reverse spelling is Ananym in which Wikipedia described it as a word whose spelling is derived by reversing the spelling of another word.
Now if you wanted to see the list of anagram you can view a comprehensive list of Panganiban anagram here.
This can be considered as a training tool for me in my SEO workshop ska wala lang, napagtripan ko lang.Google+
