Pangram

A pangram (Greek: pan gramma, "every letter") or holoalphabetic sentence is a piece of text which uses every letter of the alphabet. Interesting pangrams are generally short ones; constructing a sentence that includes the fewest repeat letters possible is a challenging task. However, pangrams that are slightly longer yet enlightening, humorous, or eccentric are noteworthy in their own right.

In a sense, the pangram is the opposite of the lipogram, where the aim is to omit one or more letters.

Today, pangrams are frequently used to display typefaces.

By far the most well-known pangram is, "The quick brown fox jumps over a lazy dog." Frequently this is the sentence used to test out new typewriters, presumably because it includes every letter of the alphabet. Curiously, this sentence is often misquoted by changing "jumps" to "jumped." The past tense version, lacking an s, is not a pangram. Often, too, it is misquoted as "the lazy dog" rather than "a lazy dog." This error is not as grievous; the sentence remains a pangram, just a slightly longer one.

Perfect pangrams

A pangram in which each letter occurs only once is the pinnacle of the pangram game. This is difficult to achieve without resorting to obscure words and proper nouns; note that purists disapprove of using initials.

A variant tries to make a word or phrase containing at least all letters with diacritical marks:

Self-enumerating pangrams

A particularly interesting kind of pangram arose from some verbal horseplay between Douglas Hofstadter, an AI researcher and writer for Scientific American, Rudy Kousbroek, a Dutch linguist and essayist, and Lee Sallows, a British electronics engineer and all-round word virtuoso. Hofstadter posed the problem of sentences that describe themselves, prompting Sallows to devise the following: "Only the fool would take trouble to verify that his sentence was composed of ten a's, three b's, four c's, four d's, forty-six e's, sixteen f's, four g's, thirteen h's, fifteen i's, two k's, nine l's, four m's, twenty-five n's, twenty-four o's, five p's, sixteen r's, forty-one s's, thirty-seven t's, ten u's, eight v's, eight w's, four x's, eleven y's, twenty-seven commas, twenty-three apostrophes, seven hyphens and, last but not least, a single !". Kousbroek published a Dutch equivalent, which spurred Sallows, who lives in the Netherlands and reads the paper where Kousbroek writes his essays, to think harder about this problem in order to solve it more generally. Initial attempts to write a program for this came to naught, but after a while he decided to construct a dedicated piece of hardware, the Pangram Machine. This accepts a description of the initial sentence fragment, and tries to fill in the blanks.

Uses of pangrams

Pangrams are used for a number of purposes other than games. For example, the pangram The quick red fox jumps over the lazy brown dog was developed by Western Union to test Telex/TWX data communication equipment for accuracy and reliability. Also, like the lorem ipsum text, pangrams are often used to display how a certain font will appear.
