A palindrome is a word, phrase, number or any other sequence of units (like a thread of DNA) which has the property of reading the same in either direction (the adjustment of spaces between letters is generally permitted). The word palindrome comes from the Greek words palin (back) and dramein (to run) meaning running back. Writing literature in palindromes is an example of constrained writing.

According to Bill Bryson's Mother Tongue: English & How It Got That Way (p. 227): "Palindromes... are at least 2,000 years old. The ancient Greeks often put 'Nipson anomémata mé monan opsin' on fountains. It translates as 'Wash the sin as well as the face.' The Romans admired them, too, as demonstrated by 'In girum imus nocte et consumimur igni' ('We enter the circle after dark and are consumed by fire'), which was said to describe the action of moths."

Palindromes occur in many western languages, but they are particularly prevalent in English due to the wide variety and frequent reversal of letter pairs within words.

Japanese palindromes, called kaibun, rely on the hiragana syllabary, like the word "shinbunshi" (newsprint). Their syllabary makes it possible to make very long palindromes.

Chinese palindromes are relatively easy to create due to the structure of written Chinese. For example: 我愛媽媽,媽媽愛我 ("I love Mom, Mom loves me") --- this is usually the first palindrom learned by Chinese kids. Numerous palindroms can be created by replacing "媽媽"(Mom) with any person. As a result, only very special palindromes are worth mentioning.

Symmetry by sound

In Japanese:

  • Ta-ke-ya-bu ya-ke-ta (竹薮焼けた) - A bamboo grove has been burned.
  • Wa-ta-shi ma-ke-ma-shi-ta-wa (私負けましたわ) - I have lost.
  • Na-ga-ki yo-no to-ho-no ne-bu-ri-no mi-na me-za-me na-mi-no-ri-bu-ne-no o-to-no-yo-ki-ka-na (長き世の 遠の眠りの 皆目覚め 波乗り船の 音の良きかな) - Tanka

The Islandic music-band Sigur Rós composed a song on their album Ágćtis Byrjun, which partly sounds the same, playing forwards or backwards. Not only symmetric from the notes, but also symmetric in the sound by mixing the reverse music over the original. The song - named Staralfur - can be downloaded at their website under http://www.sigur-ros.co.uk/media/index (http://www.sigur-ros.co.uk/media/index).

The interlude from Alban Berg's opera, Lulu is a palindrome.

Symmetry by the words

Some palindromes use words as units rather than letters. They Might Be Giants released a single called I Palindrome I, the lyrics of which include the word palindrome: "Son I am able," she said, "though you scare me." "Watch," said I, "beloved," I said, "watch me scare you though." Said she, "able am I, Son."

Another example:

  • You can cage a swallow, can't you, but you can't swallow a cage, can you?

Of course, all Chinese palindromes are also of this type.

Symmetry by the lines

Still other palindromes take the line as the unit. The poem Doppleganger was composed by James A. Lindon.


Entering the lonely house with my wife
I saw him for the first time
Peering furtively from behind a bush --
Blackness that moved,
A shape amid the shadows,
A momentary glimpse of gleaming eyes
Revealed in the ragged moon.
A closer look (he seemed to turn) might have
Put him to flight forever --
I dared not
(For reasons that I failed to understand),
Though I knew I should act at once.

I puzzled over it, hiding alone,
Watching the woman as she neared the gate.
He came, and I saw him crouching
Night after night.
Night after night
He came, and I saw him crouching,
Watching the woman as she neared the gate.

I puzzled over it, hiding alone --
Though I knew I should act at once,
For reasons that I failed to understand
I dared not
Put him to flight forever.

A closer look (he seemed to turn) might have
Revealed in the ragged moon.
A momentary glimpse of gleaming eyes
A shape amid the shadows,
Blackness that moved.

Peering furtively from behind a bush,
I saw him for the first time,
Entering the lonely house with my wife.

In genetics, a palindromic DNA sequence can form a hairpin.
