The letter D is the fourth letter of the Latin alphabet.



The Semitic letter DÔlet probably developed from the logogram for a fish or a door. In Semitic, Ancient Greek (Modern 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 letter D generally takes the voiced alveolar plosive value, IPA in most languages that use the Roman alphabet, including English. In Welsh d when doubled (dd) has the value , like English th in this.

Digraphs of D are rare in English, although other languages use DH or DD for a voiced dental fricative (some Celtic languages) or an aspirated voiced dental plosive (some Indo-Aryan languages), or use affricates DZ, DV, or DZH.

In Cantonese, the sound /d/ means a little bit, from the ancient use of the character 的 (in the phrase "兀的") in Chinese written language. Since 的 is no longer used in this way, Hong Kong residents invented a new character 啲 (which is not supported in many Chinese systems), or simply write D instead.
