The letter D

In English, the letter D is the fourth letter and third consonant of the alphabet. D represents a voiced alveolar stop, which means it is sounded when the tongue is placed at the alveolar ridge (the roof of your mouth behind your teeth) and the tongue is pushed off with sound from the vocal cords. D’s origins can be traced to the Phoenician dalet, meaning door. The letter D is a musical note, has a value of 500 in roman numerals, and in typography, can be as heavy and imposing as Blackoak or as delicate and elegant as Gotham Thin, plus everything else in between.
