Braille

n. system of writing for the blind where configurations of raised dots represent letters and numerals

v. write or spell in braille

The braille system, devised in 1821 by Frenchman Louis Braille, is a method that is widely used by blind people to read and write. Each braille character or cell is made up of six dot positions, arranged in a rectangle containing two columns of three dots each. A dot may be raised at any of the six positions to form sixty-four (26) combinations, including the combination in which no dots are raised. For reference purposes, a particular combination may be described by naming the positions where dots are raised, the positions being universally numbered 1 to 3, from top to bottom, on the left, and 4 to 6, from top to bottom, on the right. For example, dots 1-3-4 would describe a cell with three dots raised, at the top and bottom in the left column and on top of the right column, i.e., the letter m. In braille, pages are separated by a line so that you can feel going across the page.
