Have you ever noticed that some words read the same whether you read them backward or forward? That is a palindrome, and they appear everywhere—even this sentence contains one!
What Is a Palindrome?
Palindromes can be a word, phrase, string of numbers, or even a piece of music. The word palindrome comes from the Greek “palindromos,” which means “running back again.”
Usually, a palindrome consists of one, two, or maybe three words, but they can be much longer. The longest palindromic sentence is a staggering 21,012 words. It is an unbelievable feat by scientist Peter Norvig and contains nothing but unique words.
Fun Fact: There is also a unique fear of palindromes known as “aibohphobia.” Fortunately, it isn’t official because it is also a palindrome!
Examples of Palindromes
Now that you know what palindromes are, here are a few examples:
- Racecar (a car used for racing)
- Hannah
- Kayak (a type of canoe)
- Madam
- Peep
- Elle
- Eve
- Otto
- Rotator (a part that allows something to rotate)
- Deified (to worship something or someone as a god)
- Taco Cat
What Are the Different Types of Palindromes?
Palindromes come in many forms. Let’s review the ones you are most likely to encounter.
Single-Word or Character-Unit Palindromes
These are your basic palindromes. As the name suggests, they consist of a single word or a string of characters.
- Noon
- Mom
- Level
Multi-Word Palindromes
Multi-word palindromes consist of more than one word. They are usually phrases, although some sentences can also be considered multi-word palindromes.
- Top spot
- Dog god
- Loot tool
Sentence Palindromes
These palindromes are full sentences. They differ from multi-word palindromes because they include both a subject and a predicate.
- Too hot to hoot.
- Dennis sinned.
- Go hang a salami, I’m a lasagna hog (yes, really).
Number Palindromes
Number palindromes are exactly what they sound like. There is one, in particular, you might recognize if you have ever played around on a calculator. There are also many other “SFW” examples of number palindromes.
- 101
- 2882
- 777 (also known as a repdigit)
Musical Palindromes
There are several types of musical palindromes. The first occurs when an entire musical composition sounds the same forward and backward. Another example is a musical motif that is identical in both directions. You could even argue that the band ABBA forms a musical palindrome!
- The notes A, C, D, C, A played in succession
- The bass solo from Paul Simon’s “Call Me Al.”
- Johann Sebastian Bach’s “Crab Canon”
Date Palindromes
You can also have palindromic dates. Many people like to celebrate these days because they feel special, even though they are fairly common.
- 02/02/2020
- 5/25/25
- 4/21/24
Final Thoughts
You will find palindromes in literature, math, music, and even on your calendar. You likely already use them in your everyday writing and speech. It can be fun to play with language by deliberately incorporating palindromes. So, long live the palindrome—provided you don’t have aibohphobia, of course.
