Pangram

A pangram (Greek: παν γράμμα, pan gramma, "every letter") or holoalphabetic sentence is a sentence using every letter of a given alphabet at least once. Pangrams have been used to display typefaces, test equipment, and develop skills in handwriting, calligraphy, and keyboarding.

The best known English pangram is "The quick brown fox jumps over the lazy dog." It has been used since at least the late 19th century, was utilized by Western Union to test Telex / TWX data communication equipment for accuracy and reliability, and is now used by a number of computer programs (most notably the font viewer built into Microsoft Windows) to display computer fonts. An example in another language is Victor jagt zwölf Boxkämpfer quer über den großen Sylter Deich, containing all letters used in German, including every umlaut (ä, ö, ü) plus the ß. It has been used since before 1800.

Short pangrams in English are more difficult to come up with and tend to use uncommon words. A perfect pangram contains every letter of the alphabet only once and can be considered an anagram of the alphabet; it is the shortest possible pangram. An example is the phrase "Cwm fjord bank glyphs vext quiz" (cwm, a loan word from Welsh, means a steep-sided valley, particularly in Wales). Most such examples are not usually understood even by native English speakers, and so arguably are not really English pangrams. Perhaps the most easily understood perfect pangram is "Mr Jock, TV quiz PhD, bags few lynx"—but it includes three abbreviations (Mr, TV and PhD).
