D is the fourth letter in the Latin alphabet. Its name in English is spelled dee (pronounced /diː/), plural dees.
History
The Semitic letter Dâlet probably developed from the logogram for a fish or a door.
In Semitic, Ancient Greek, and Latin, the letter was pronounced /d/; in the Etruscan alphabet the letter was superfluous, but still maintained (see letter B). Greek letter: Δ (capital) or δ (small) (Delta).
The minuscule (lower-case) form of D consists of a loop and a tall vertical stroke.
In handwriting, it was common to start the arc to the left of the vertical stroke, resulting in a serif at the top of the arc. This serif was extended while the rest of the letter was reduced, resulting in an angled stroke and loop.
The angled stroke slowly developed into a vertical stroke.
Usage
In most languages using the Latin alphabet, the letter d represents the sound /d/, but in the Vietnamese alphabet it represents the sound /z/ in the north and /j/ in the south.
