The Semitic letter Dâlet probably developed from the logogram for a fish or a door. There are various Egyptian hieroglyphs that might have inspired this. In Semitic, Ancient Greek, and Latin, the letter was pronounced /d/; in the Etruscan alphabet the letter was superfluous but still retained (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. It developed by gradual variations on the majuscule (capital) form. 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. In Fijian it stands for the prenasalized stop /nd/.[2] In some languages where voiceless unaspirated stops contrast with voiceless aspirated stops, d represents an unaspirated /t/, while t represents an aspirated /tʰ/. Examples of such languages include Icelandic, Scottish Gaelic, Navajo, and the Pinyin transliteration of Mandarin.

The numeric character references in HTML and XML are "D" and "d" for upper and lower case, respectively.

< Computer programming languages

Books in this subject area deal with the D programming language: an object-oriented, imperative, multi-paradigm system programming language originated as a re-engineering of C++, but even though it is predominantly influenced by that language, it is not a variant of it. D has redesigned some C++ features and has been influenced by concepts used in other programming languages, such as Java, C# and Eiffel.
