The word pangram comes from the Greek pan gramma, which means “every letter.”
A pangram is a sentence that contains every letter of the alphabet. You can use a pangram in typing exercises to involve (and thereby test) all the alphabetical keys; you can also use pangrams to display all the letters of a font’s typeface to check their appearance.
The most well-known pangram in the English language is: “The quick brown fox jumps over the lazy dog.” In case you were wondering, English isn’t the only language that uses pangrams; many other languages do so, too.
Here is an example from French, and here is one from Spanish.
