Palindromes

 

The word palindrome is derived from the Greek palíndromos, meaning running back again (palín = AGAIN + drom–, drameîn = RUN). A palindrome is a word or phrase which reads the same in both directions. Some simple examples are:

 

RACECAR
...
DEED
.....
LEVEL
.....
PIP

ROTOR
......
CIVIC
.....
POP
........
MADAM

EYE
...........
NUN
......
RADAR
....
TOOT

 

Words like
LIVE
and
STRAW
(which read
EVIL
and
WARTS
palindromes
but the "phrases"
backwards) are not themselves
LIVE EVIL
and
STRAW WARTS
are. A
palindrome
is not necessarily a single word.

 

The longest single English word in common usage which is a palindrome is
REDIVIDER
, although the contrived chemical term
DETARTRATED
is two letters longer. In Finnish there is a 25-letter palindromic word:
SOLUTOMAATTIMITTAAMOTULOS
which means the result from a measurement laboratory for tomatoes, although technically it is a compound of four words. There is also the equally long
SAIPPUAKUPPINIPPUKAUPPIAS
which means soap cup trader.

 

When creating reversible sentences, it is usually accepted that punctuation and word spacings are ignored, and so the famous
MADAM, I'M ADAM
is a valid palindrome.

 

Palindrome Varieties

 

There are two other types of
palindrome
, although neither is particularly common. The first is the
word-unit palindrome
. As the name suggests, these are palindromes in which the words form the same sentence in either direction, e.g.
WOMEN UNDERSTAND MEN; FEW MEN UNDERSTAND WOMEN.
Occasionally these are also traditional palindromes, such as in
I DID, DID I
? but this only happens when each word is itself a traditional palindrome.

 

The other kind of palindrome is the
mirrored palindrome
. These are palindromes which are graphically reversible. Not all letters in
mirrored palindromes
necessarily have symmetry about a vertical axis (
A, H, I, M, O, T, U, V, W, X
) since some letters are (more or less) mirror images of others (e.g.
L
and
J
). Therefore a mirrored palindrome is not necessarily also a traditional palindrome. Punctuation and spaces cannot be ignored when creating mirrored palindromes. When reversed
A TOYOTA
becomes
ATOYOT
A
which, strictly speaking, is not the same.
WOT TOW
, although fairly meaningless, is a valid mirrored palindrome. Of course, with this type of palindrome, it is important whether upper or lower case letters are used:
bid
is a mirrored palindrome, but
BID
is not
