D
The fourth letter of the Latin alphabet. The Semitic letter Dâlet probably developed from the logogram for a fish or a door. In Semitic, Ancient Greek (Modern Greek /ð/) and Latin the letter was pronounced /d/, in the Etruscan alphabet the letter was superfluous but still maintained (see letter B). Greek letter: &Delta (capital) or δ (small) (Delta). Delta represents the letter D in the NATO phonetic alphabet.

In Cantonese, the sound /d/ means a little bit, comes from the ancient use of the character 的 (in the phrase "兀的") in Chinese written language. Since 的 is no more used in this ancient way, Hongkongers invented a new character 啲 (which is not supported in many Chinese systems) or simply write D instead.
In context, D is also:
- The symbol of deuterium, an isotope of hydrogen.
- A musical note
- The Roman numeral for 500
- The stock symbol for Dominion Resources Inc. VA
- A standard size dry cell battery.
- a programming language; see D programming language.
- The variable d for diameter of a circle.
- The symbolism for the differential operator.
