(40-43) English words are made of 26 letters, and palindromes and anagrams are two kindsof word games about spelling. A palindrome is a word or a sentence that reads thesame from left to right or from right to left, __40__ , “eye,” “Bob,” “my gym,” and“Was it a car or a cat I saw?” An anagram of a word or words is made by putting theletters of the word or words in a different way. Look at the words and their anagramsbelow. Can you think of other possible anagrams of these words? Anagrams are often longer words that don’t really mean anything but are fun tosay. Sometimes they can even mean something __42__ , like when a common word,“restaurant,” becomes “Eat rats, run!”  Actually, palindromes and anagrams are __43__ . Palindromes can be used to learnmathematics and make music. Anagrams are also a good way to hide something. Inhistory, people often hid their important studies in anagrams. Can you think of anyother way to use them?
