Other forms: pangrams
A pangram is a sentence that uses every single letter in the alphabet at least once. It's much more challenging to come up with short pangrams than longer ones.
The most famous English pangram is "The quick brown fox jumps over the lazy dog," a sentence that's been used since the 1800s to test typewriter ribbon and compare different fonts and typefaces. Once you start trying to write your own, you'll soon see how challenging it can be to use every letter. Pangram, coined from the Greek pan-, "all," and gramma, "that which is written, " is also known as a "holoalphabetic sentence."
