w

The twenty-third letter of the English alphabet and the eighteenth consonant, representing the voiced labio-velar approximant sound /w/. As a grapheme, 'W' is unique in English for being the only letter whose name ('double-u') describes its shape rather than representing a distinct sound. It functions as an abbreviation for watt in physics, a symbol for west on maps, a size designation for wide, and the chemical symbol for tungsten.
