Palindromes, anagrams, and spoonerisms

Definition: palindromes are words or phrases that read the same forwards as backwards. The adjustment of punctuation and spaces between words is generally permitted. Palindromes have been found throughout history, some as old as 80BCE. The word palindrome was coined from Greek roots pali, back anddromos, direction way by English writer Ben Jonson in the 1600s.

Anagrams are rearranged letters in a word or phrase to make another word or phrase. From the Greek wordanagramma 'letters written anew'. Technically, any word or phrase which exactly reproduces the letters in another is an anagram; e.g., saltine = entails. However, the goal of serious or skilled anagrammists is to produce anagrams which reflect or comment on the subject. Such an anagram may be a synonym or antonym of its subject, a parody, a criticism, or praise.
Example: George Bush  =  He bugs Gore.

A reversal of sounds in two words. Named for William Spooner, an English clergyman and scholar, around 1900. American English has over 600,000 words (and growing), more words than any other language. Therefore, there's a greater chance that any accidental transposition of letters or syllables will produce rhyming substitutes that make some sense.
