“vertical” palindrome

October 30, 2011

suns,      mow,      pod

These are some pretty cool words. If you flip them upside down they still spell the same thing. They’re like vertical versions of a palindrome. I wrote a little python script and ran in on the standard linux dictionary file, and, to my knowledge, these are the only words in the English language that have this property. There were other words that spell different things when flipped upside down, like “owns” and “sumo”, but these three were the only ones that were the same. I didn’t count SOS as a word, but that’s pretty cool since it’s both a ‘vertical’ and a standard palindrome.
