English Braille, also known as Grade 2 Braille, is the braille alphabet used for English. It consists of around 250 letters (phonograms), numerals, punctuation, formatting marks, contractions, and abbreviations (logograms). Some English Braille letters, such as ⠿ ⟨for⟩, correspond to more than one letter in print. There are three levels of complexity in English Braille. Grade 1 is a nearly one-to-one transcription of printed English and is restricted to basic literacy. Grade 2, which is nearly universal beyond basic literacy materials, abandons one-to-one transcription in many places (such as the letter ⠿ ⟨for⟩) and adds hundreds of abbreviations and contractions. Both Grade 1 and Grade 2 have been standardized. "Grade 3" is any of various personal shorthands that are almost never found in publications. Most of this article describes the 1994 American edition of Grade 2 Braille, which is largely equivalent to British Grade 2 Braille. Some of the differences with Unified English Braille, which was officially adopted by various countries between 2005 and 2012, are discussed at the end. Braille is frequently portrayed as a re-encoding of the English orthography used by sighted people. However, braille is a separate writing system, not a variant of the printed English alphabet.
