racecar, rotor, level, civic, madam

See any similarity between those words?

These words can be read the same way in either direction. It's called Palindrome.
Not only words, but phrases, numbers, and unit could also be a palindrome.
for example: 12321, step on no pets, dammit i'm mad, etc.

Hey, there are indonesian palindromes too!
kasak, kusuk, kasur rusak, etc. (I think Indonesian Palindromes are harder to find...)

I don't really think that this is an important matter, but it's just that even the things which we considered as unimportant sometimes have a name (and a cool one too). So it means that there are people out there thinking that palindrome are something worth to think.

...right now i'm still thinking what are the other indonesian palindromes...
