What is a palindrome?

A palindrome is a word or phrase that can be read the same way backward or forward, as with the words redivider, kayak, and civic.

Palindromes are most often used to be creative and have fun with words. You might see them in ads to catch your attention or a creative writing teacher might ask the class to write palindromes to help students think more creatively.

In biology, a palindrome describes a sequence of nucleotides in DNA that matches a reverse line. The possible nucleotide combinations are A-T and C-G, and the pairs can match up in any order. Sometimes they line up palindromically, as when CCTAGG matches up with a sequence of GGATCC.

Example: One of the most famous palindromes is “Never Odd or Even,” which has the same letters backward and forward.

Where does palindrome come from?

The first records of the term palindrome come from around 1630. It comes from the Greek palíndromos, meaning “recurring.” A word or phrase that is spelled the same way backward as it does forward might be thought of as having recurring letters.

Palindromes are a literary device similar to alliteration or rhyme schemes, which allow writers to add an extra layer of written complexity to their works. Sometimes a product or brand with a palindromic name is more memorable, such as the Honda Civic, Xerox printers, Elle magazine, and OXO cooking products.
