A word that is spelled the same forwards and backwards is called a "palindrome." Examples include "level," "radar," and "racecar." Palindromes can be found in various forms, including words, phrases, and even numbers. They often serve as a fun linguistic curiosity, showcasing the flexibility and playfulness of language. The concept of palindromes extends beyond just individual words; entire sentences can be structured to retain the same sequence of letters when reversed, although they can be more challenging to create. Overall, palindromes provide a unique way to engage with language and wordplay.
