Detailed Explanation

Grade 2 Braille is the standard form of contracted Braille used in the United States. Unlike Grade 1 Braille (uncontracted), which spells out every letter, Grade 2 uses over 250 contractions and abbreviations to represent common words and letter combinations. For example, "the" is represented by a single character rather than three separate letters. The ADA specifically requires Grade 2 Braille on all tactile signs because it is the form that Braille readers are trained to read.

Examples
