A palindrome is something that reads the same forward and backward. The idea is simple, but it can appear in different forms, including words, numbers, and phrases.
For a single word, the letters match in reverse order. Examples include level, radar, and madam. For numbers, the same pattern applies, such as 121 or 1331.
Phrases are a little different. When checking whether a phrase is a palindrome, people usually ignore spaces, punctuation, and capitalization. That is why Never odd or even counts as a palindrome. If you remove the spaces and read it backward, it stays the same.
- Word: level
- Number: 1221
- Phrase: Was it a rat I saw
Not every repeated pattern is a palindrome. For example, banana is not one, because reversing it gives a different result. The key test is always the same: if the full sequence matches in both directions, it is a palindrome.
