De (Cyrillic)
De (Д д; italics: Д д) is a letter of the Cyrillic script.
De commonly represents the voiced dental plosive /d/, like the pronunciation of ⟨d⟩ in admit.
De is romanized using the Latin letter D.
History
The Cyrillic letter De was derived from the Greek letter Delta (Δ δ).
In the Early Cyrillic alphabet its name was добро (dobro), meaning "good".
In the Cyrillic numeral system, De had a value of 4.
Form
The major graphic difference between De and its modern Greek equivalent lies in the two descenders ("feet") below the lower corners of the Cyrillic letter. The descenders were borrowed from a Byzantine uncial shape of uppercase Delta.
De, like the Cyrillic letter El, has two typographical variants: an older variant where its top is pointed (like Delta), and a modern one (first used in mid-19th-century fonts) where it is square. Nowadays, almost all books and magazines are printed with fonts with the second variant of the letter; the first one is rather stylish and only a few popular text fonts use it (the most known example is "Baltika" designed in 1951-52 by V. G. Chiminova and others).
