d
dHistory of the letterd. The letter may have started as a depiction of a door in Egyptian hieroglyphic writing (1). The earliest form of the sign in Semitic writing is unknown. About 1000bce in Byblos and other Phoenician and Canaanite centers, the sign was given a linear form (2), the source of all later forms. In Semitic languages the sign was calleddaleth, meaning “door.” The Greeks changed the name todelta, but they retained the Phoenician form of the sign (3). In an Italian colony of Greeks from Khalkis (now Chalcis), the letter was made with a slight curve (4). This shape led to the rounded form found in Latin writing (5). From Latin the capital letter came unchanged into English. In Greek handwriting the triangle of the capital letter was given a projection upward. During Roman times the triangle was gradually rounded (6).

d, letter that has retained the fourth place in thealphabet from the earliest point at which it appears in history. It corresponds toSemiticdaleth and Greekdelta (Δ). The form is thought toderive from an early pictograph, possiblyEgyptian, indicating the folding door of a tent. The rounded formD occurs in theChalcidian alphabet, whence theLatin alphabet may have acquired it by way of theEtruscans. The letter has retained the rounded form that it had in the Latin alphabet until the present day.

From these forms and from theuncial arose theCarolingian and our ownminusculed.

The sound consistently represented by the letter in Semitic, Greek, Latin and the modern languages of Europe is the voiced dentalstop. In English this sound, as well as the unvoiced sound represented byt, has become alveolar, that is to say, is pronounced by the pressure of the tongue upon the gums rather than upon the teeth.

Theetymologicalvalue ofd in words of native English origin is generally the same as that of Germant (th), Sanskritdh, Greekθ, Latinf (initial) ord orb (medial), all being derived fromdh in the parent Indo-European speech (e.g., Englishdo, Germanthun, Sanskritdadhāmi). In some other instancesd is derived from Indo-Europeant when thed originally resulting from thet has been subsequently altered by the change familiarly known asVerner’s law. The occurrence of this change depended on the place of the Indo-European accent (so, for example, the priord inhundred, Sanskritśatám, Latincentum).
